Patan Durbar Square

Patan Durbar Square complex is perhaps the most photographed of the three durbar squares. Located in the heart of Patan city, this was once the palace of the kings of Patan. The square is a display of Newari architecture that had reached its pinnacle during the reign of Malla kings who were great builders and patrons of the arts. The palace has three main courtyards: the central and the oldest is Mul Chowk. To the west of the complex are a dozen free standing temples of various sizes and built in different styles. A masterpiece in stone, the Krishna Temple, Bhimsen Temple, the Golden Temple of Hiranya Varna Mahavira and Sundari Chowk mark the artistic brilliance of the Newar craftsment of that era. The Sundari Chowk with the sunken bath of Tusha Hiti, showcases exquisite woodcarvings, stone and metal sculpture. Like the other palaces, Patan Durbar Square also houses a temple dedicated to Taleju Bhawani.
