About Magö Lighthouse

The Magö lighthouse, built in 1914, is a gray concrete cylindrical tower situated near the southern end of Magö island. This structure, standing 6 meters tall with a focal height of 13 meters, guides vessels at the southeastern entrance to Slite Hamn. Its light produces three flashes, alternating between white, red, and green, every nine seconds. This signaling system allows mariners to differentiate safe passages from hazards. The site is open to the public, though the tower itself is closed.

Why it matters: This lighthouse is important for maritime safety, providing critical guidance for vessels entering Slite Hamn. Its directional light system precisely marks safe channels and warns of shallow waters, helping to prevent groundings and ensure efficient harbor traffic.
