Jaisalmer
Marvel at Jaisalmer's extraordinary merchant havelis — Patwon Ki Haveli (5 interconnected mansions, the grandest with 60 balconies of lace-like carved yellow sandstone), Salim Singh Ki Haveli (peacock-adorned roof arches), and Nathmal Ki Haveli (built by two brothers — left and right halves slightly different reflecting their artistic rivalry).
Patwon Ki Haveli's topmost floor interior is now a government museum and the most elaborate — worth paying the entry fee for.
