'''Harmaja''' ({{langx|sv|Gråhara}}) is an island and a [[lighthouse]] outside [[Helsinki]], south of the [[Suomenlinna]] sea fortress. The island has been functioning as a landmark since the 16th century. A landmark structure was built on the island in the 18th century and a light house in 1883.<ref>{{cite rowlett|fin1a|access-date=January 19, 2016}}</ref> The first lighthouse was only 7.3 m high and it soon proved to be too low. In 1900 the height was doubled by creating a rectangular brick building on a granite base. A large [[foghorn]] alerted ships in fog and in bad visibility. Harmaja received the world's first directed and undirected radio beacon in 1936. The lighthouse is fully automated today.

There is also a [[pilot station]] on the island.

During the [[1952 Summer Olympics]] this was the center of the [[Sailing at the 1952 Summer Olympics|Olympic sailing event]].
