Military Museum, History museum in Sumur Bandung, Indonesia.

Museum Wangsit Mandala Siliwangi occupies a late-Romanticism colonial building on Jalan Lembong 38, constructed between 1910 and 1915 as housing for Dutch officers. It stands on a 4,176 m² plot with a 1,674 m² two-storey building. Its rooms display traditional Sundanese weapons such as kujang, keris and tombak, modern armoured vehicles and artillery, plus a gallery of paintings depicting romusha forced labour.

Built between 1910 and 1915 as housing for Dutch officers, the building later served as a hideout during the Japanese occupation and housed the Siliwangi Division headquarters in 1949–1950. On 23 January 1950 it was the main target of the APRA attack led by Captain Raymond Westerling, in which 79 Siliwangi soldiers died, including Major Adolf Lembong. It was inaugurated as a museum on 23 May 1966 by Colonel Ibrahim Adjie.

The museum displays items that reflect the evolution of Indonesian military traditions, from traditional weapons to modern equipment used by the armed forces. Visitors can see how warfare and military practices have changed over time.

The museum is open Monday to Thursday from 08:00 to 13:00 WIB, Friday until 10:00, and Saturday until 12:00. Entry is by voluntary donation, and guides are available to take visitors around and recount the history.

The collection includes original furniture used during the drafting of Indonesia's independence declaration, a rare record of that historic moment. Visitors can also see artifacts from the Siliwangi Division's military operations, an important unit in the early history of the armed forces.
