Fort Ahui, also known as Fuerte de Ahui, is located on the Lacuy Peninsula near the city of Ancud on Chiloé Island. The fortification was built in 1779 by order of the Spanish colonial authorities to defend the strategic entrance to the Bay of Ancud from foreign naval attacks. As part of the region's defensive system, the fort featured massive stone walls and a battery of eleven cannons that controlled the maritime routes. During the Chilean War of Independence, this site served as one of the last royalist strongholds in South America before being captured by republican forces in 1826. Today, the well-preserved ruins, the gunpowder magazine, and the observation points are designated as a National Monument of Chile. Visitors can explore the colonial military architecture while enjoying expansive views of the Pacific Ocean and the rugged coastline.
