Fort Tolukko sits on a rocky promontory on the northeastern coast of Ternate Island, about 8 kilometres from the town centre. Built by the Portuguese in 1540, it is one of the oldest surviving European structures in eastern Indonesia. The cliff-top position was chosen for its commanding view — from the battlements you can see across the Molucca Sea in three directions, with the cone of Tidore's volcano visible to the south.
The fort is smaller than Fort Oranje and more dramatic in setting. The stonework is in reasonable condition for its age, and the combination of the ruins with the volcanic landscape makes it one of the most atmospheric historical sites in Maluku. A small caretaker maintains the site.
Getting there requires an ojek (motorcycle taxi) or rented motorbike — the road hugs the coast and passes through clove and nutmeg groves that recall the trade that built these fortifications.
