This octagonal temple was one of the finest in the square and was originally a viewing point for nobles observing festivals and rituals. The Mandap was built during the 17^th century by King Jitamitra Malla and was used as a rest house by the travelers and pilgrims. It has an open hall at the lower level. It was totally destroyed by the 1934 A.D. earthquake; it was recently reconstructed with assistance from Germany.
