A tiny, beautifully-situated fort surrounded by a vivid tropical garden, Benteng Tolukko was the first Portuguese stronghold on Ternate (1512). It's better-preserved that the town's two other benteng , inviting a stroll on the battlements for yet another stunning view across to Tidore and Halmahera. If it's locked, knock on the door of the family home next door; they'll have the key.
