Patan Durbar Square is situated at the centre of the city of Lalitpur in Nepal. It is a UNESCO World Heritage Site. Patan is the oldest of all the three cities of Kathmandu valley. It is best known for its artistic heritage. The city is situated on a plateau across Bagamti River. The city is surrounded by 4 stupas at 4 corners of Patan, one at each corner of its cardinal points and is believed to be built by the Emperor Ashoka. The former royal palace complex is the center of Patan’s religious and social life and houses a museum containing an array of bronze statues and religious objects. There are three main courtyards or chowks in Patan Darbar Square – central Mul Chowk, Sundari Chowk and Keshav Narayan Chowk. The Sundari Chowk holds in its center a masterpiece of stone architecture, the royal bath called Tushahity.
The square was heavily damaged in the earthquake of 25 April, 2015.
