Caves of Altamira Reopen: Spanish Culture Ministry to Defy Scientists’ Warnings

Cave of Altamira, SpainThe Spanish Culture Ministry have announced that the Caves of Altamira the so-called Sistine Chapel of Paleolithic art are to reopen after eight years of closure, despite serious warnings from scientists that the world-famous ancient drawings and polychrome rock paintings within may suffer irrevocable damage from moisture generated by visitors.

In a statement to reporters on Tuesday, Spanish Culture Minister Angeles Gonzalez-Sinde and the sites board of directors announced that public access will resume before the end of this year, albeit on an unspecified, restricted basis.

The cave complex located in the Cantabria region of northern Spain, and first discovered in 1879 was closed to the public in 2002, after green fungus generated by the body heat and breath of visitors was found to be forming on the facade of paintings in the main hall.

A replica of Altamira located just a few hundred metres away in a museum in the nearby town of Santillana del Mar has drawn 2.5 million visitors since 2001. But local government officials in Cantabria have lobbied for the reopening of the real thing, and successfully, after Altamiras board of directors last week voted in favour of resuming public access at the site which at its peak of popularity in the 1970s attracted as many as 3,000 people per day.

Altamira is an asset we cannot do without, the Cantabria regions president, Miguel Angel Revilla, commented.

Altamiras Paleolithic art is between 14,000 and 20,000 years old, and represents the first set of prehistoric cave paintings ever discovered. Several famous painters, including Pablo Picasso, are said to have been inspired by its charcoal and ochre images, which include several iconic depictions of red and black bison.

Decay of the paintings caused by a change in the fragile atmosphere in the cave was first detected in 1977, and Altamira was subsequently closed for five years, before reopening in 1982 with heavily restricted access. The waiting list to view the caves which were inscribed as a UNESCO World Heritage Site in 1985 later grew to the point where visitors had to book up to three years in advance.

Its Revillas intention to now try and attract heads of state to visit the caves. In recent years Revilla has been forced to turn down requests to visit Altamira from former French president Jacques Chirac and Mexican president Felipe Calderon, but he has expressed a hope that Barack Obama will be one of the first people to people to witness the cave complex’s ancient masterpieces after access resumes.

I have already written the invitation letter, Revilla said, and in English.

The caves have recovered from the damage, but to open them again is not a good idea. The risks are immeasurable.

Scientists will greet the news of Altamiras imminent reopening with no shortage of dismay. Just last year, the governments main scientific research body, the CSIC, strongly recommended that the caves remain closed. The people who go in the cave have the bad habit of moving, breathing and perspiring, said CSIC researcher Mariona Hernandez-Marine.

We have made it very clear that it should not be reopened at this time, commented Sergio Sanchez Moral, director of a two-year CSIC investigation at Altamira. The caves have recovered from the damage, but to open them again is not a good idea. The risks are immeasurable.

Decay from moisture generated by visitors is a problem at many ancient sites around the world. Lascaux Cave in France, adorned with similarly venerable prehistoric paintings, has fought its own battle with fungus and has been closed for long periods over the last few years (read about the battle to preserve ancient rock art around the world in this article).

Extensive work had to be carried out on the Great Pyramid of Giza in the early 90s, using robots, in order to improve ventilation, after increased humidity from visitors began eroding the monuments stones (more on that in this article). Dr Zahi Hawass head of Egypts Supreme Council of Antiquities last year warned that a number of tombs in the Valley of the Kings, including the tomb of King Tut, may have to close soon if they are to be preserved.

Altamiras paintings are described by UNESCO as masterpieces of creative genius, and as humanitys earliest accomplished art.

Its thought that the caves location, deep underground where it is largely isolated from external climatic influences, is what has allowed its ancient artistic treasures to be preserved for so many centuries. As anticipation of Altamiras reopening grows, it remains to be seen whether they will endure much longer.

Heavy Rain in Rome Causes Major Damage to Domus Aurea and Trajan’s Baths

Sad news today for Italy: part of the complex archaeological structure surrounding Nero’s ‘Golden House’ in Rome his extravagant palace between 64-68 AD has collapsed following heavy rain.

The Domus Aurea, as it is known, is one of the treasures of the ancient Roman world. Although it has been mainly closed to the public in recent years due to efforts to fend off encroaching damp and decay, it is a unique archaeological site and an important part of Italy’s heritage.

The site is structurally complex and includes important buildings from the reigns of Nero and Trajan. When Nero committed suicide in 68 AD, his imperial residence was largely gutted and precious materials taken for use elsewhere in ancient Rome. Some of the building itself was filled with earth and buried. Today the Domus Aurea lies mainly underneath Colle Oppio, although it originally extended as far as the Palatine and Caelian hills on the other side of the Colosseum.

In 69 AD, Vespasian took power and built the Flavian amphitheatre (i.e., the Colosseum named after the bronze statue of Nero as Colossus Colossus Neronis which stood in the Domus Aurea) which is about 100 metres or so from the entrance to the Domus Aurea. The emperor Trajan came to power in 98 AD and it was during his rule that an elaborate bathing complex was built right on top of Nero’s buried golden palace.

Luciano Marchetti described the situation as one of extreme alarm

The area damaged is about 60 square metres of the ceiling of one of the halls of Trajan’s baths, known as the fifteenth room, according to La Repubblica. The roof fell through at about 10am on Tuesday morning. Pictures of the collapse as seen from the top of Colle Oppio were published on the paper’s website.

Further collapses are possible according to the special commissioner for the site Luciano Marchetti. He described the situation as one of extreme alarm. He said there is an immediate risk of further damage, and to mitigate this they need to begin conservation work straight away for which secure funding is needed. Work done on the site so far has cost EUR 2 million. According to Marchetti, a further EUR 10 million is needed to completely secure and preserve the site.

According to La Repubblica, archaeological excavations were underway at the site but officers at the scene don’t believe that anyone has been trapped or injured. Officials are now working to make the area safe and to prevent further rain from damaging the area that has been exposed.

Fracture Zones and Groundwater Endanger Tombs in Valley of Kings

Line Drawing of the Fractures - Photo Credit Richard Parizek, Penn StateAncient choices made by Egyptians digging burial tombs may have led to today’s problems with damage and curation of these precious archaeological treasures, but photography and detailed geological mapping should help curators protect the sites, according to a Penn State researcher.

“Previously, I noticed that some tomb entrances in the Valley of Kings, Luxor, Egypt, were aligned on fracture traces and their zones of fracture concentration,” said Katarin A. Parizek, instructor in digital photography, department of integrative arts. “From my observations, it seems that tomb builders may have intentionally exploited these avenues of less resistant limestone when creating tombs.”

Fracture traces are the above-ground indication of underlying zones of rock fracture concentrations. They can be between 5 and 40 feet wide, but average about 20 feet and can be as long as a mile. Lineaments are similar geological features that exceed one mile in length. Geologists suggest that fracture traces are good locations for drilling water wells and probably the highly fractured rock made it easier for the Egyptians to dig tombs.

Archaeologists try very hard to mitigate flooding in the tombs, but it becomes even harder if there are tombs flooding that no one knows about.

Working with Richard R. Parizek, professor of geology and geoenvironmental engineering, Parizek has now looked at 33 of the 63 known tombs in the Valley of Kings. She reported her results yesterday at the annual meeting of the Geological Society of America in Portland:

“We have now documented nine tombs in detail, photographing and mapping the entire tombs inside and out, and preliminary observations have been made in another nine, which still have to be mapped in detail,” said Parizek. “We have recorded 14 more tombs through field observations, but still need to map and photograph these as well.”

Of the 63 tombs in the Valley of the Kings, so far 30 have been identified by Parizek as lying on fracture traces, two lie diagonal to a trace and one is completely off of this type of geological structure.

The importance of these geological features is not just that they allow easier tomb creation, but the fracture traces are natural entry points for water, which sometimes damage tombs. “We have seen evidence of seven separate flood events in four tombs so far,” said Parizek.

“Archaeologists try very hard to mitigate flooding in the tombs, but it becomes even harder if there are tombs flooding that no one knows about,” says Parizek.

Because so many of the tombs are located on the traces, the water runs into the tombs destroying wall and ceiling paintings and causing the tomb surfaces to spall or flake off. Even if archaeological curators divert water away from the entrances of known tombs, they may be directing the water to currently undiscovered tombs and flooding them.

The geological information the team has been gathering is now allowing archaeologists to plan better ways to stop the flooding of both known and unknown tombs by diverting the water away from traces and exposed entrances.

Parizek also notes that archaeologists are using this geological information along with archaeological clues to explore for new tombs and other archaeological sites in the Valley of Kings. In February 2006, KV63 was discovered by professor Otto Schaden.

“This tomb is localized along master joints immediately adjacent to a zone of fracture concentration that we mapped in 2002,” said Parizek. This discovery supplied evidence the Parizeks’ original hypothesis that tombs were dug on fracture traces and into fracture zones is correct.

The researchers hope to investigate and map the geology of more tombs in the future and to combine the photographs and maps to create 3-D images of the tombs.

It is not only groundwater that threatens the ancient tombs. The humidity and fungus generated by tourists breath and sweat is damaging the soft stone and paintings and carvings thousands years old. Closing Tutankhamun, Nefertari and Seti I’s tombs were the first step in the SCA’s new plan to protect the Valley of the Kings. Other tombs get added protection such as a cool lighting system to spread the number of visits over the course of the day. Eventually an entire ‘Replica Valley (of the Kings)’ for the tourists will be installed on the cliff side of the real Valley.

UNESCO’s Final Report on Damage Assessment in Babylon

030425-F-7203T-008.JPGAfter 4 years of research – at a quite ‘sensitive’ and not-so-safe area, Imust admit – UNESCOfinally released it’s Final Report on Damage Assesment in Babylon by the International Coordination Committee for the Saveguarding of the Cultural Heritage of Iraq. Be the report not that world-shocking, we all know by now that both Saddam Hussein as well as the Coalition Forces are to blame, the report does clearly devide which damage was inflicted upon the Babylon archaeological area before the start of the Iraq war, and which was brought upon ‘Camp Alpha’ post-2003.

Damage to the archaeological site that occurred before 2003

  • Parking lots – Flat areas covered with gravel were built in scattered areas of the city. (Of which some were later used by the MNF-IIraq as airfield.)
  • The Al-Hawliyah canal and it’s lakes – The moat surrounds the city of Babylon and has a lenght of 4.5km and a width of 15. The bottom and sides of the moat are lined with cement. The canal is linked to three lakes, of which the largest is 29ha.
  • Artificial earthen mounds – Established under the ‘International Babylon Festival’ plan.
  • The Palace and buildings surrounding it, as well as restaurants and service buildings constructed in the center of the archaeological site.
  • Improper restaurations and reconstructions – Amongst others the Southern Palace of Nebuchadnezzar, the northern portion of the Processional Way, the temple of Minmakh and the temple of Nabu-sha-Hare, the eastern portion of the inner wall, the Babylonian houses and the Greek Theatre. In particular, the use of concrete for the foundations of the reconstructed Greek Theatre is in clear contravention of internationally acknowledged standards.
  • Firing positions – Defensive trenches in scattered areas of the city. The spoil from one of these trenches contains archaeological material including a glazed vessel.
  • Damage to previous archaeological excavations – The lack of appropriate maintenance and protection caused major damage to the exposed remains from rain, wind, ground water, salt, plans and human activity.

BABYLON, Iraq March 28, 2005.

Damage sustained to the site in 2003 after the MNF-1 entered the city

The UNESCO report on the use of Babylon as a military base:”a grave encroachment on this internationally known archaeological site. During their presence in Babylon, the MNF-I and contractors employed by them, mainly KBR, directly caused major damage to the city by digging, cutting, scraping, and leveling. Key structures that were damaged include the Ishtar Gate and the Processional Way.

The military presence in the city and the establishment of a military zone, entailing fortification and defensive measures caused both indirect and direct damage:

  • hescoExcavation works, pits & trenches – Many trenches of different sizes were dug in different parts of the city. Only to often the soil removed was not preserved. In at least one of the trenches pottery fragments and baked brick fragments with Nebuchadnezzar’s name inscribed were found. This trench has begun to collapse, causing additional damage.
  • Cutting works – Horizontal cutting into a mound, removing deposits. Again, only to often soil was removed, mixed with sand from other locations and not preserved.
  • Scraping and leveling works – On several archaeological areas and tells, which were then covered with sand and gravel. Some of them were treated with chemicals in addition. This operation covered broad areas of Babylon and entailed the use of heavy equipment to compact the soil, which may have destroyed any antiquities beneath the surface. The effects of chemical treatment on the archaeological sub-surface layers are not yet known.
  • HESCO containers – Which area a ‘Concertainer Defence Wall System’ were filled with soil from the city of Babylon containing pottery fragments and backed brick fragments. Some of these are still in use.
  • Barbed wire and steel stakes – The barbed wire is not limited to a specific location. The damage in this case was caused by the implantation of stakes in archaeological ground and on several tells and walls, as happened to a wall in the central area and a wall in the sacred precinct.
  • Ishtar Gate – The Ishtar Gate serves as a ritual gate leading into the northern part of the inner city. The damage to the gate includes smashed bricks on nine of the bodies of the animals adorning the gate. These animals depict the legendary dragonsnake, the symbol of Marduk, the god of the city of Babylon.
  • Southern portion of Processional Way – Major damage can be observed in the southern part of the Processional Way, which was rediscovered during the Babylon Revival Project excavations in 1979. Starting from the Nabu-sha-Hare Temple, the effects of heavy vehicle wheels are clear, breaking the paving of the street. Three rows of 2-ton concrete blocks were placed in the middle of the Processional Way on top the paving by heavy vehicles, which is itself an encroachment. These blocks were removed by helicopter on November 29, 2004 to prevent further damage to the Processional Way. In addition, a row of HESCO containers with soil taken from the eastern wall of the sacred precinct were placed on the way, and barbed wire was attached by steel stakes to the wall itself and in the middle of Processional Way. There is also a cut in the wall itself with a length of 2.5 m, a depth of 50 cm, and a height of 1.5 m.
  • Many of the reconstructed features and buildings have suffered damage, including the Inner Wall, the Temple of Ninmakh, the Temple of Ishtar, the Nabu-sha-Hare Temple, the royal palaces and the Babylonian houses. Part of the roof of the Ninmakh Temple collapsed and cracked. Fractures and openings can be seen in the walls of various buildings. The presence of the MNF-1 in Babylon made these structures inaccessible, preventing the SBAH from maintaining their normal procedures of monitoring and repair. A contributing factor to the damage in the Ninmakh Temple may have been the vibration resulting from constant air traffic coming from the close-by helipad. Also, the movement of heavy vehicles within the site caused undefined damage to the archaeological sub-surface layers by churning up or compressing earth.

Looting & damage to artefacts and archives during the war

The Ishtar Gate, Atual IraqDuring the war in 2003, the archaeological city was subjected to encroachment and damage. The Nebuchadnezzar and Hammurabi museums were broken into and everything in the two museums was stolen. Fortunately, the objects exhibited in the two museums were plaster replicas rather than originals, but this did not prevent them from being stolen. Some of these replicas were found scattered and destroyed in the grounds of the two museums. The Project Management Headquarters (Study Centre) and the Museum Office also attracted the thieves and robbers. Whatever could not be stolen was burned. Everything in the Babylon Library and Archive was destroyed, including important reports, maps, and studies on the results of excavation and preservation works undertaken by the Babylon Archeological Restoration Project.

You can read the full report at the UNESCOwebsite. But after taking a glance at even just this short summary, one can not help but wonder if archaeologists should advise the military on Middle East heritage?

Fire Engulfs Archaeological Area of Solunto in Sicily

Fire-fighting: A Losing Battle

Wildfires are a big problem in southern Italy. Every year they sweep the tinder-dry countryside and often threaten forests, farmers’ land and human habitation. In Sicily and Campania in particular, ancient heritage sites can also be in danger from summer fires. Despite state publicity about not throwing cigarette butts out of car windows and well-publicised hot-lines (no pun intended) for reporting local fires, it seems that the authorities are fighting a losing battle.

This year looks like it will be no different, with the countryside around Palermo in Sicily being one of the first to suffer. This week, on 21 June, a blaze tore through scrub land near the town of Bagheria, 10 km east of Palermo on the north Sicilian coast. Despite efforts from a fire-fighting plane and helicopter, it took many hours to get the fire under control and during that time it unfortunately spread to the valuable archaeological area of Solunto. The extent of the damage to the Roman ruins is not yet known.

The Roman Ruins of Solunto

While Solunto may not be the most important archaeological site in Sicily, it would still be a sad loss if it has been seriously damaged by fire. Its ruins amount to no more than some mosaics and the lower part of buildings and columns and it is certainly no match for the grandeur of the temples at Agrigento or the impressive expanse of mosaics at the imperial villa at Piazza Armerina.

But what Solunto lacks in well-preserved ancient architecture, it makes up for in its history. As one of only three main Phoenician settlements in Sicily (the other two being Zis in present-day Palermo, and Motya, now Mozia on Sicily’s west coast), Solunto certainly deserves some respect, dating back as it does to 700 BC when it was called Kfra by the Phoenicians. It would later be known as Solus by the Greeks when they conquered it in 396 BC, and Soluntum by the Romans after they took it in 254 BC. Later that century the town was abandoned and was left uninhabited and undiscovered until the sixteenth century. Almost all of its buildings are Roman and the ruins of a small theatre are still visible.

According to local news sources, the local fire brigade has not yet ruled out the possibility that the fire was started on purpose. It would be sad indeed if Italy’s cultural heritage had arsonists, as well as time, against it.
