About Biando Hang North Breakwater Lighthouse

A black cylindrical concrete tower, standing 9 meters tall and topped with a single yellow horizontal band, marks the end of the main north breakwater at Biando Hang. The light emits a red signal, flashing once every 4 seconds. The tower’s focal height is 10 meters, and it has a geographic range of 10.4 nautical miles. The structure was originally a round red concrete tower, but the breakwater was extended and the light relocated around 2020. The site is accessible to visitors, though the tower itself is closed.

Why it matters: This light aids vessels entering and exiting Biando harbor, with its relocation around 2020 reflecting adaptations to port infrastructure.
