Click to view map Coordinates: | Declared a National Monument (now Provincial Heritage Resource) on 1995 09 25. The prefabricated cast-iron lighthouse at Mahlongwa was dismantled and re-erected at this location to protect shipping from the Aliwal Shoal. It was equipped with a 700mm focal distance, group-flashing optic. The lens platform was floated on a bed of mercury and the original light source was a petroleum vapour burner, the second last such to use this light source and the first to be fully automated in 1961 when the light was converted to electric operation.
