Castillo de San José or Castle of Saint Joseph was built between 1776 and 1779 on the orders of the Spanish King Carlos III. It was primarily constructed to have a military purpose and to provide work for the islanders, who lost their jobs following volcanic eruptions earlier in the century. It was most famously known as the Fortaleza del Hambre or the Hunger Fortress.
