Kathmandu, Nepal's capital, is set in a valley surrounded by the Himalayan mountains. At the heart of the old city’s mazelike alleys is Durbar Square, which becomes frenetic during Indra Jatra, a religious festival featuring masked dances. Many of the city's historic sites were damaged or destroyed by a 2015 earthquake. Durbar Square's palace, Hanuman Dhoka, and Kasthamandap, a wooden Hindu temple, are being rebuilt.
