Take a tour of the "world's only continuously lived-in fort"

What would it be like to live in a 12th century hill fort in India? Ask the 5,000 residents who still inhabit the fort in Jaisalmer in the western part of the country. The BBC's Sanjoy Majumder takes visitors on a narrated tour with a slideshow.

The photos showcase the beautiful architecture of the fort, including a temple and mansions of wealthy merchants.
