About Singangseo Lighthouse

Also known as: Singangseo (Suri Do, Shingangso, Shinganseo)

This concrete cylindrical tower, built in 1992, stands 8 meters tall with a focal height of 12 meters. It is painted in two sections, with the upper half black and the lower half yellow, and features a double gallery. The lighthouse is mounted on a round concrete pier extending from the sea. Its light emits a single white flash every 10 seconds, visible for 11 nautical miles. The site is accessible, but the tower itself is closed to the public.

Why it matters: This lighthouse warns vessels of a reef off the northern tip of Yeondo, a significant navigational hazard in the coastal waters near Yeosu-si.
