Märket ("The Mark") is a small 3.3-hectare (8.2-acre) uninhabited skerry in the Baltic Sea between Sweden and Finland (in the area of the autonomous Åland Islands), with a lighthouse as its salient manmade feature. Märket has been divided between the two countries since the Treaty of Fredrikshamn of 1809 defined the border between Sweden and the Russian Empire as going through the middle of the island. The Finnish side of the island is part of the Municipality of Hammarland and is the westernmost land point of Finland. The Swedish part of the island is itself divided by two counties of Sweden: Uppsala County (Östhammar Municipality) and Stockholm County (Norrtälje Municipality).
The name Märket ('the Mark') probably comes from its usefulness as a navigation mark before there were lighthouses. The route between Sweden and Åland has a passage about 27 kilometres (15 NM) (17 mi) long over open sea. Before the lighthouse was erected, the island and its shallows were dangerous navigational hazards, which seafarers tried desperately to avoid. In 1873, as many as 23 ships were grounded on the Swedish coast and its archipelago trying to avoid Märket, and eight of them were shipwrecked. Märket is detached from the main Åland archipelago, with the closest island more than 10 km (6.2 mi) away, and the closest harbor, Berghamn, 23 km (14 mi) away in Eckerö. There is no deep harbor; the island can only be reached with boats. There are small, barely surfacing rocks northwest of Märket, called Märketshällor ("stones of Märket"), which are too small to sustain vegetation.
There is a lighthouse on the Finnish side of the current border, which has been unmanned and automated since 1979. When it was built by the Grand Duchy of Finland (then part of the Russian Empire) in 1885, the island was considered a no-man's land, so the lighthouse was simply built upon the highest point of the island. However, the location selected was within the Swedish portion of the island.
As a result, the border was adjusted in 1985 so that the lighthouse is now located on Finnish territory. The adjustment was carried out such that no net transfer of territory occurred, and the ownership of the coastline was unchanged so as not to interfere with each country's fishing rights.
