Tombua (Tombwa, Porto Alexandre) (2?)

Date unknown (1920s or early 1930s). Active (?); focal plane 11 m (36 ft); white or green light, depending on direction, occulting three times every 9 s. 8 m (26 ft) tripod skeletal tower mounted atop a 1-story building. No photo available but Google has an indistinct satellite view. This is one of several lights in Namibe reported to have been rehabilitated in 2008; the satellite view suggests that the light was moved to a skeletal tower next to the building. Located at the end of a sand spit protecting the harbor of Tombua (called Porto Alexandre under colonial rule), marking the west side of the harbor entrance. Site status unknown. PT-5606; Admiralty D5436; NGA 25716.
