Flötjan Lighthouse

The Flötjan Lighthouse is located on a small rocky islet in the Åland Sea, Finland, approximately 18 kilometers southwest of Mariehamn. The lighthouse was first built in 1908, but the original structure was severely damaged during World War II. A new concrete tower was constructed in 1953 and automated in 1959.

The Flötjan Lighthouse stands at a height of 22 meters, with a focal height of 26 meters, and has a range of 10 nautical miles. The tower is cylindrical in shape, with a double balcony and lantern, and is marked with a red and white color scheme. The lighthouse is situated on a rock and concrete base, and its light characteristic is a flashing white light that occurs every 20 seconds.

The Flötjan Lighthouse has an interesting history, having been damaged during World War II and subsequently rebuilt. Today, the lighthouse remains an important aid to navigation, particularly for the Stockholm-Mariehamn-Tallinn ferry that passes just to the west of the island. Despite being automated, the lighthouse continues to play a vital role in ensuring the safety of mariners in the Åland Sea.
