Jaisalmer Fort is one of the largest forts in the world. It is situated in Jaisalmer city in the Indian state of Rajasthan. It was built in 1156 AD by the Bhati Rajput ruler Rao Jaisal, from where it derives it name. The fort stands proudly amidst the golden stretches of the great Thar Desert, on Trikuta Hill, and has been the scene of many battles. Its 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 "Golden Fort".This fort, popularly known as the 'Sonar quila' by the locals, is located in the very heart the city, and is one of the most breathtaking monuments in the locality.
