Patan's Durbar Square presents an example of mastery in urban design with a complex of temples fronting the old royal palace of Patan. The many shrines here offer a medley of architectural styles, with the stone temple of Krishna Mandir, dedicated to the Hindu deity Krishna, standing out with its workmanship. The palace building contains a number of chowks, or courtyards. The Sundari Chowk has in its centre a sunken bath with its walls embellished with stone carvings. The Golden Window in the palace is a masterpiece in repousse art. UNESCO has declared Patan Durbar Square a World Heritage Site.
