Jaisalmer Fort is situated in Jaisalmer city in Indian state of Rajasthan. It was built in 1156 AD by the Bhati Rajput ruler Rawal Jaisal, from where it derives it name. It is one of the largest forts in the Desert.

Its massive yellow sandstone walls are a tawny lion color during the day, turning to a magical honey-gold as the sun sets and camouflages the fort making it appear a part of the picturesque yellow desert. Thus, no wonder, it is also known as the "Golden Fort". It is also known by the name "Sonar Killa"

This is the world's only living fort and about a quarter of city's population live in the fort.
