Fort Oranje is the most visible remnant of the Dutch colonial period in Ternate, a four-bastioned fort built in the early seventeenth century on the waterfront near the town centre. The Dutch East India Company (VOC) used it as their administrative headquarters for the Moluccas — the control point for the most profitable trade in the world at the time.
The fort has been converted into government offices, which means it is accessible but not formally set up as a museum. The outer walls, bastions, and gateway are largely intact and impressive in scale. Inside, some original cannon remain on the bastions. The waterfront position, with views across the strait to Tidore, gives you an immediate sense of why the Dutch were so determined to control this specific piece of geography.
The surrounding area has several other remnants of the colonial period — old Dutch graves, the remains of warehouses, and the street grid of what was once a VOC company town.
