Amantubillah, Palace of the Mempawah kingdom in Pulau Pedalaman, West Kalimantan, Indonesia

Amantubillah is the palace complex of the Mempawah kingdom in Pulau Pedalaman village, Mempawah Timur. It consists of a main building and two wings: the main building once housed the sultan's throne and family, the right wing was used for preparations and banquets, and the left wing served as an audience hall and administrative office. The complex is dominated by green, and the gate bears the inscription "Mempawah Harus Maju, Malu dengan Adat".

Amantubillah was built during the reign of Gusti Jamiril, titled Panembahan Adi Wijaya Kesuma, the third sultan of Mempawah (1761-1787). A fire in 1880, under the ninth sultan Gusti Ibrahim, titled Panembahan Ibrahim Mohammad Syafiuddin (1864-1892), destroyed the palace. It stood again on 2 November 1922, rebuilt under the eleventh sultan Gusti Muhammad Taufik Accamaddin (1902-1943).

The name Amantubillah means "I believe in Allah", and the gate carries the motto "Mempawah Harus Maju, Malu dengan Adat". The main building now holds the Mempawah kingdom museum, with the throne, royal umbrellas, kris and ceremonial dress; the right wing serves as the palace pendopo and the left wing houses royal relatives.

The complex is divided into a main building, now the Mempawah Kingdom museum, a right wing used as the palace pendopo, and a left wing where royal relatives live. In the grounds visitors can see the sultan's former bathing pool, now dry and no longer fed by the channel from the Mempawah tributary. The site stands in Desa Pulau Pedalaman, Mempawah Timur, Mempawah Regency.

The name Amantubillah means "I believe in Allah", and the gate carries the inscription "Mempawah Harus Maju, Malu dengan Adat". In the palace grounds visitors can see the sultan's bathing pool, now dry and unused because silt and a blocked channel have cut it off from the Mempawah tributary.
