Bomarsunds fästningsruiner

See one of Åland’s most remarkable historical monuments!

The fortress of Bomarsund was built during the years 1832-1854. Åland was Russian at the time and the fortress was intended for the Russian contingents on the islands. The establishment was calculated for 5000 men, which by Åland standards was an enormous building project. It had a big impact on the Åland society and still today the expression “the Bomarsund era” remains.

The Bomarsund era got an abrupt ending. The establishment was thoroughly ruined when attacked by the allied English-Frenchmen. Even though the Bomarsund fortress was a parentheses in the Åland history, the consequences of it’s rise and fall remains today; Åland became a demilitarised zone.

The ruins of the fortress is now one of Åland’s most remarkable
historical monument.

On the other side of the channel, next to the bridge of Prästö, is a
small museum where pictures and objects from Bomarsund are on display.
