The granite used for the tower construction was quarried directly from the island itself.
The lighthouse tower includes a basement that once housed a fog siren, which has since been removed.
During the Battle of Bengtskär in 1941, the lighthouse was heavily damaged by shelling and hand-to-hand combat.
The light signal can be seen from a distance of approximately 20 nautical miles.
The light source was converted from kerosene to electricity in 1968.
The lighthouse was fully automated in 1995, marking the end of permanent staffing by lighthouse keepers.
The chapel located inside the tower is the southernmost church in Finland.
The island is almost completely devoid of vegetation due to its exposure to harsh sea winds and salt spray.
Migratory birds often use the island as a resting point, making it a key site for ornithological observation.
Bengtskär Lighthouse is the tallest lighthouse in the Nordic countries, standing 52 meters above sea level on an isolated rocky islet in the Archipelago Sea. Completed in 1906, the granite structure serves as a navigational landmark and houses a museum dedicated to local maritime history and the 1941 Battle of Bengtskär. The tower remains a functional lighthouse with an automated light signal. Visitors can explore living quarters that reflect the daily lives of keepers and their families during the lighthouse's operational era. The island is accessible exclusively by boat from the mainland. The site also functions as a hotel, offering overnight stays within the historical lighthouse tower. Its location is strategically significant, situated on the outermost edge of the Finnish archipelago.
