Museum Perumusan Naskah Proklamasi, Independence museum in Menteng, Indonesia

The Museum Perumusan Naskah Proklamasi occupies a two-storey Art Deco building of 1,138 m² on a 3,914 m² plot in Menteng, designed by J.F.L. Blankenberg and built in 1920. Its rooms recreate the 1945 scene with replica furniture, including the round table and the piano under the staircase where Sukarno and Hatta signed the proclamation text.

Built in 1920 to a design by J.F.L. Blankenberg, the building was bought in 1931 by the insurance company Nillmij and later served as the British General Consulate. During the Japanese occupation it became the residence of Rear Admiral Tadashi Maeda, then the British military headquarters after September 1945. Rented by the British Embassy until 1981, it was transferred to the Department of Education and Culture on 28 December 1981 and inaugurated as a museum on 24 November 1992.

The building holds the memory of a pivotal moment when Indonesian leaders gathered here to shape their nation's independence. The rooms display furnishings and personal objects from that period, allowing visitors to sense how people moved and worked in these spaces.

The museum occupies a two-storey 1920 Art-Deco building of 1,138 m2 on a 3,914 m2 plot, entered from Jalan Imam Bonjol in Menteng. The four exhibition rooms follow the order of the events, from Maeda's living room to the typing room, so visitors move through them in sequence. A bunker about 5 m wide, 3 m long and 1.5 m high sits in the back yard.

The furniture in the museum, including the round-table meeting set, the piano and the guest chairs, are replicas: the house was looted in 1945, so only the room layout is original. Behind the building lies a secret bunker about 5 m wide, 3 m long and 1.5 m high, where Rear Admiral Maeda stored state documents.
