Cape Columbine Lighthouse is a 15 metre square masonry tower which is painted white. The lighthouse is built on the rising ground at Castle Rock near Paternoster. It became necessary to construct a lighthouse here, because the sea is hazardous with submerged rocks including the Britannia Reef and Soldiers Reef and there have been numerous shipwrecks in the past. This is usually the first lighthouse sighted by ships coming from Europe. The lighthouse is also equipped with a Chance Brothers twin diaphone fog signal and a radio beacon. Cape Columbine is known to be the last manned lighthouse to be erected on the South African Coast.
