Fort Tohula — sometimes spelled Torre, and not to be confused with the larger Tahula — is the second of the surviving Spanish forts above Soasio. It sits on a separate ridge a short walk uphill from the town and is considerably smaller and more ruinous than its neighbour. The walls are still standing in places, and the platform on which the fort was built gives another good viewpoint across the strait to Ternate and Halmahera.
Tohula sees few visitors and the path up is sometimes overgrown, but the climb is worth it for anyone interested in the colonial military architecture of the spice islands. The two Spanish forts together formed an interlocking defensive system covering the approaches to the sultan's town, and seeing them in sequence makes the strategic logic clear. Ask in Soasio for a local guide who can point out the original path between the two.
