My recent travels in India took me to Ajanta, about two hours' drive outside of Aurangabad, in the Indian state of Maharashtra (where they're making perfectly drinkable wine these days, by the way).
The nearby small town of Ajanta gives its name to the collective of 29 caves carved out of a sheer wall of rock in a horseshoe-shaped river canyon, completed in the period 200BC to 500AD in the name of Buddhism. Several are temples, but most are dormitories originally built for temporarily housing Buddhist monks, as well as travellers and itinerant spice traders. The spice route passed through here on the way from Southern India, where they still grow wonderful black pepper, on its way to the main port at what is now Mumbai, where spices were loaded for shipment on to Arabia and Europe. I had read about the caves in guide books, and had to wrangle a little with my husband to make the time to see them during our woefully short visit to India, but despite a complex and long journey, they were thoroughly worth it.
