Cape Horn Lighthouse, Lighthouse at Cape Horn, Tierra del Fuego, Chile

Cape Horn Lighthouse stands at the southernmost tip of the Tierra del Fuego archipelago where Atlantic and Pacific waters converge. The compound includes the light tower, residential buildings, a small chapel, and wooden walkways that cross the island's boggy terrain.

The lighthouse was inaugurated on 17 November 1991, built by the Chilean Navy. Its tower is a cast-iron structure made in 1900 by Lever, Murphy & Co. of Caleta Abarca, which served until 1987 as the lighthouse at San Antonio. It was moved to Punta Espolón to mark the southernmost point of the Tierra del Fuego archipelago.

The lighthouse is staffed by Chilean Navy personnel, and since 2006 a wooden and brick building of about 60 m² has housed the keeper and family. A small wooden chapel stands nearby. Jules Verne's novel Les Naufragés du « Jonathan » ends with the Kaw-Djer settling on Horn Island, where he has a lighthouse built.

The lighthouse stands on Punta Espolón, at 62 m above sea level on the southeastern tip of Horn Island, and is reached only by expedition cruise between Ushuaia and Punta Arenas. Landings depend on weather and sea state, so time ashore is short and often cancelled. The nearest settlement is Puerto Toro; no road or regular service connects the island.

The lighthouse's metal tower was built in 1900 by Lever, Murphy & Co. of Caleta Abarca and served at San Antonio until 1987, when it was moved south and re-erected here; it was inaugurated on 17 November 1991. The cylindrical cast-iron structure is painted in horizontal white and red bands.
