Jaisalmer
Wander through Sonar Quila (Golden Fort) — one of the world's few living forts (3,000+ people still reside inside). This UNESCO World Heritage 12th-century sandstone citadel rises 80 metres above the desert plain and contains palaces, Jain temples (beautiful 12th–16th century carved marble), havelis, and the royal palace of the Bhati Rajput rulers.
The Jain temples inside the fort (Shantinath and Ashtapadi temples) have extraordinary 800-year-old carved white marble — among India's finest Jain temple art. Photography is restricted inside.
