Sasana Wiratama, also known as Museum Monumen Pangeran Diponegoro (Diponegoro Monument Museum) is a museum complex in Yogyakarta. The complex consists of a museum and a monument which commemorates the struggle of Prince Diponegoro, an 18th-century Javanese prince and a National Hero.
The building where the museum stands was handed down to the government of Yogyakarta by the heir of Diponegoro, Raden Ayu Kanjangteng Diponegoro, to function as a monument after signing a transfer letter with Nyi Hadjar Dewantara and Kanjeng Raden Tumenggung Purejodiningrat. Beginning from mid-1968 until 19 August 1969, a monument was built on the pringgitan building that adjoined with the pendopo at the center of the complex. The project was initiated by Major General Surono who was the Commander of the Military District and was inaugurated by President Suharto. This place was then named Sasana Wiratama, Javanese “place for soldiers”.
