El Tostón Castle (Castillo del Tostón) is in the north of Fuerteventura, in the town of El Cotillo, and like most buildings in the Canary Islands, started to be built after the Castilian arrival.

After Fuerteventura was conquered, El Cotillo gained importance as a key trading port, so the tower was built in the 15th century to help defend the island against the constant pirate attacks.

Over time, El Tostón Castle has become an absolute symbol for El Cotillo, thanks to being a part of the living history of Fuerteventura.

It is constructed from stone, extracted from a nearby cave, has a circular base and was able to accommodate 12 men. Within its structure, a total of 3 cannons could be installed on the upper part of the tower, while the lower part stored the required gunpowder to activate said cannons. Currently, the Castle serves as an exhibition centre.

Next to it, you can find Piedra Playa, and a few kilometres to the south you’ll find the El Tostón Lighthouse, which now holds a Fishing Museum.
