About Tsuboga Se Lighthouse

Also known as: Tuboga

Constructed in 1969, the Tsuboga Se lighthouse stands 14 meters tall on a concrete cylindrical tower. The structure features a tapered form with a wider top section, painted black and distinguished by a red horizontal band. Its light emits a single white flash every five seconds, visible for 12.4 nautical miles. The focal height of the light is 17 meters above sea level. Site access is permitted, but the tower itself is closed to the public, maintaining its operational status.

Why it matters: The lighthouse warns mariners of the Tsuboga (Tuboga) Se hazard, a submerged rock or reef, guiding both local fishing boats and commercial vessels.
