Jaisalmer Jaisalmer has constantly held an extraordinary place in the imagination of explorers national and foreign alike as Indias supreme desert outpost. Situated in the sandy area of the Thar Desert, Jaisalmer was once part of the legendary Silk Route. Being a trade route, passing convoys brought prosperity to the city that found appearance in imposing castle constructed by rich traders. Built in native yellow stonework, now sanctified as Jaisalmer stone, the city quite literally looks like a Golden City as it has come to be recognized.
