Museum Tri Daya Eka Dharma, Military history museum in Bukittinggi, Indonesia

Museum Tri Daya Eka Dharma occupies a former rest house of the Governor of Sumatra at Jalan Panorama No. 22 in Bukittinggi. Its rooms display hundreds of wartime objects: long and short rifles, cannons, ammunition, grenades, radio transmitters, signal receivers, telephones, and Indonesian and foreign military uniforms. Photographs of generals, of the detention sites of the revolutionary heroes, and of Indonesian presidents from 1945 to 2004 line the walls.

Mohammad Hatta opened this museum in 1973, converting the building that once served as the Governor of Sumatra's rest house into a military memorial. This transformation marked an important moment in preserving local military history.

The name comes from three elements of strength and single devotion, reflecting the traditional Minangkabau philosophy of Tigo Tungku Sajarangan. Visitors notice how this meaning shapes the way the space honors local values.

The museum stands on Jalan Panorama in Kayu Kubu, Guguk Panjang, on the same street as the Panorama park area of Bukittinggi. The sources give the address as number 22 in one account and number 24 in another, so check locally before setting out. The building was formerly the rest house of the Governor of Sumatra.

An American-made AT-16 aircraft, Harvard B-419, used against the Revolutionary Government of Central Sumatra in 1958, stands outside the museum. This plane is one of the rarer exhibits that often catches visitors' attention immediately.
