History

The lighthouse is found on the southern point of Dassen Island, off the western coast of South Africa, 55 km north-west of Cape Town and 11 km west of Yzerfontein.[1] It was installed on 15 April 1893.[1] The lighthouse consists of a circular cast-iron tower that is painted in white and red bands and stands atop a brick base to height of 28 m.[1][2]

The light house signals two white flashes, separated by 10 s, every 30 s.[2] The fog horn blasts for five seconds every fifteen seconds.[2] The lighthouse is manned at all times. The island is closed to the general public, but can be visited by special permit.
