The Iso-Kraaseli Island Historical Daymark in Raahe Archipelago

The Iso-Kraaseli daymark was built in 1852 according to the plans of Albin Stjerncreutz, chief of the Ostrobothnian navigation district. 25 metres above the sea level, 18 metres above the ground. Even earlier, there were a daymark and a pilot’s hut on the island. According to a sailing guidebook from 1865, a senior pilot and three pilots were on duty in the pilot’s hut. They had steering documents for all three entrance routes to Raahe. The Iso-Kraaseli daymark and the tower of Raahe’s old church were important signposts for the central route. In the Kraaseli daymark, the heartwood tree running all the way through the roof forms a two-metre pole on top of the structure, which was used as a signal pole. The daymark’s sea-facing walls are white, while the other parts are red.

In summertime, you can access the archipelago on small cruise boats or by canoe – or go stand up paddling either on your own or on guided tours, or with your own or rented equipment or boat. Normally, the cruise boat charter transport season starts in May and operates all the way until October. The summer schedules for daily departures are published in the Archipelago cruises and transport website.

In winter, when the ice is firm enough, the islands can be accessed by sleigh and other means, weather permitting. Skiing, walking and cycling on the frozen sea is a favourite pastime for locals too. Read more about the services available in the archipelago in
