San Joaquin Castle

San Joaquin Castle is an inland fortification in La Cuesta, on the road that connects Santa Cruz de Tenerife and San Cristóbal de La Laguna, in Tenerife, Canary Islands, Spain. In 1586, Governor D. Juan Núñez de la Fuente ordered the construction of several platforms at the site, designed by the Italian Leonardo Torriani, which were subsequently abandoned. The current building's construction started in 1780. It was constructed to defend the interior of the island, should the coastal defenses of the island fall. The castle is square, with circular towers at each corner. It has a central courtyard, with bays on two sides. Two of the towers were used to store gunpowder.
