Two lighthouses are located near or in Cape Horn. The one located in the Chilean Navy Station is the more accessible and visited, and is commonly referred to as the Cape Horn lighthouse. However, the Chilean Navy station, including the lighthouse (ARLS CHI-030, 55°57′48.5″S 67°13′14.2″W) and the memorial, are not located on Cape Horn (which is difficult to access either by land or sea), but on another land point about one mile east-northeast.
On Cape Horn proper is a smaller 4-metre (13-foot) fiberglass light tower, with a focal plane of 40 metres (130 feet) and a range of about 21 kilometres (13 miles).
This is the authentic Cape Horn lighthouse (ARLS CHI-006, 55°58′38.3″S 67°15′45.5″W), and as such the world's southernmost traditional lighthouse.[7] A few minor aids to navigation are located farther south, including one in the Diego Ramírez Islands and several in Antarctica.
