About Maslen Nos Lighthouse

Also known as: Maslen Nos (Cape Zeitin)

The Maslen Nos lighthouse, built in 1930, stands on a rocky promontory about 7 kilometers northeast of Primorsko. This quadrilateral stone tower, standing 7 meters tall, is painted white and features a lantern and gallery. Its light is positioned 37.5 meters above sea level and emits white flashes every 17.2 seconds, visible for 16.7 nautical miles. The station includes the tower and an adjacent one-story building, likely a former keeper's residence. Since its first illumination in 1930, the lighthouse has continuously served as an active aid to navigation.

Why it matters: This lighthouse marks a significant rocky promontory, guiding vessels safely along the Bulgarian Black Sea coast and away from this natural hazard.
