Castillo de San José is an 18th-century fortress in Arrecife, Lanzarote, built during the reign of Charles III to strengthen the defense of Puerto de Naos and Arrecife's harbor front. The structure earned the popular nickname Fortress of Hunger because its construction provided employment during economic hardship. After losing military relevance, it deteriorated significantly until artist César Manrique proposed restoration and conversion into a museum in the mid-1970s. He personally directed the remodeling, preserving the fortress's character while adapting it for art display. The International Museum of Contemporary Art (MIAC) officially opened December 8, 1976. Today it houses contemporary works by Canarian, national, and international artists across upper galleries, a Canarian artists room, and sculpture gallery. A glass-enclosed semicircular dining structure serves à la carte Canarian cuisine with views of Arrecife Bay.
