Brucoli Castle, Medieval castle in Brucoli, Italy

Brucoli Castle is a fortress at the mouth of the port-canal of Brucoli, a hamlet of Augusta in the province of Syracuse, Sicily. It stands on the eastern coast, not on the Gulf of Catania, and was built to guard the canal, the maritime trade and the grain reserves stored there.

In 1467 Queen Joanna Enríquez, who had received the area from her husband King John II of Aragon, granted construction to Giovanni Cabastida, a chamberlain from Barcelona, for three generations. The fortress was built to counter Turkish expansion in the Mediterranean; later Barbary raids from North Africa were added. It stood at the mouth of the port-canal to defend against raids and control maritime trade and the wheat reserves stored there.

The castle's name recalls its older form, Castello della Bruca. Its founding is tied to Queen Giovanna Enríquez, who received the area from her husband, King Giovanni II of Aragon, and in 1467 granted construction to Giovanni Cabastida, a chamberlain from Barcelona, for three generations. Local tradition links the patron saint Nicholas of Bari to Barbary raids.

The castle stands at the mouth of the Brucoli canal-port, with the 1911 Brucoli lighthouse in the narrow strip between the fortress and the sea. Approach from the village of Brucoli, a frazione of Augusta, and look for the lighthouse to locate the site.

The castle stood at the mouth of the harbour canal, so it watched over the grain reserves that converged there as well as the sea traffic. In 1911 the Brucoli Lighthouse was built on the narrow strip between the fortress and the sea, marking the same position.
