The Helsinki Lighthouse (Finnish: Helsingin majakka; also commonly known as Helsingin kasuuni[1]Swedish: Helsingfors fyra; Helsingfors kassun) is a caisson-type lighthouse located in the Gulf of Finland, Шаблон:Convert due south of West Harbour, Helsinki.

Construction of the lighthouse began in the Suomenlinna shipyard in May 1958, and in August the same year the structure was towed to its current location and sank to rest on the seabed at a depth of Шаблон:Convert. Further work was carried out the following year, and the lighthouse was officially commissioned in September 1959.[2]

Constructed of reinforced concrete, the maximum diameter at the bottom of the submerged base is Шаблон:Convert, and that of the visible tower Шаблон:Convert.[2] The height of the visible part is Шаблон:Convert, with the light at Шаблон:Convert above mean sea level.[2]

The tower has eight storeys, with the solar-powered[2] 40W halogen light source on the top,[3] and control and technical rooms as well as operator accommodation below. In 1984, a helipad was added on top of the tower.[2]

The lighthouse is automated,[3] and operated from the control room on the Harmaja islet.[2]

There is a Finnish Meteorological Institute weather station located at the lighthouse.[4]
