Kathmandu Durbar Square (Basantapur Durbar Kshetra) is located in front of the old royal palace of the former Kathmandu Kingdom and is one of three Durbar (royal palace) Squares in the Kathmandu Valley in Nepal, all of which are UNESCO World Heritage Sites.

Several buildings in the Square collapsed due to a major earthquake on 25 April 2015. Durbar Square was surrounded with spectacular architecture and vividly showcases the skills of the Newar artists and craftsmen over several centuries. The Royal Palace was originally at Dattaraya square and was later moved to the Durbar square.
