Helsinki lighthouse, Caisson lighthouse in Gulf of Finland, Finland
The Helsinki Lighthouse rises 27.5 meters above its base structure with a maximum diameter of 19 meters at the bottom and 6 meters for the tower.
The lighthouse construction began at Suomenlinna shipyard in May 1958 and was towed to its location, sinking to rest on the seabed at 13 meters depth.
The structure represents Finnish maritime engineering excellence with its reinforced concrete design and eight-story configuration including technical rooms and operator quarters.
The lighthouse operates through remote control from Harmaja islet control room and features a helipad added in 1984 for maintenance access.
The lighthouse houses a weather station operated by the Finnish Meteorological Institute, providing real-time observations for maritime safety in the Gulf of Finland.
