Jaisalmer Fort is situated in the city of Jaisalmer, in Rajasthan, India. It is believed to be one of the very few ‘living forts’ in the world, as nearly one fourth of the old city's population still resides within the fort.
Jaisalmer Fort is the second oldest fort in Rajasthan, built in 1156 AD by the Rajput ruler Jaisal.
The fort's massive yellow sandstone walls are a tawny lion color during the day, fading to honey-gold as the sun sets, thereby camouflaging the fort in the yellow desert. For this reason it is also known as the ‘Sonar Quila’ or Golden Fort.
In 2013, Jaisalmer Fort, was declared a UNESCO World Heritage Site.
