Fort of Our Lady of the Annunciation, Portuguese colonial fort in Sirimau District, Ambon City, Indonesia.

Fort of Our Lady of the Annunciation, known as Benteng Victoria, is a stone fort in Sirimau District, Ambon. Its gate has a triangular pediment with an oval relief of a sailing ship and a Latin inscription, a band reading "NIEUW VICTORIA", and panels marked "ANNO" and "MDCCLXXV". Four columns flank the arch, two on each side; the left ones carry a banner with three white Xs above a crescent. Inside are rooms, giant cannons, wooden statues, and maps of Ambon from the 17th to 19th centuries.

Portuguese forces built the fortress in 1575 and named it Nossa Senhora da Anunciada. The Dutch captured it in 1605, renamed it Fort Victoria, and rebuilt it after an earthquake in 1754 as Nieuw Victoria.

The fort displays cannons and historical paintings of Dutch administrators who governed the region for centuries. These objects tell the story of the different powers that shaped life on the island.

The fortress serves as headquarters for the Pattimura Military Command but remains open to visitors interested in colonial architecture. It is advisable to check in advance whether access is currently available, as it still functions as an active military site.

The gate carries the inscription "NIEUW VICTORIA" and the date "ANNO MDCCLXXV" (1775), with an oval relief of a sailing ship in its pediment. The date marks the rebuilding after the 1754 earthquake, not the fort's 1575 Portuguese origin.
