The oldest remaining parts of the Jaani (St. John’s) Church were built in the end of 13th century. It was enlarged in 1865 and partially reconstructed couple of years later. The interior is mainly from the 17th century and represents Renaissance and Baroque styles.
In the church graveyard is an old tombstone from the year 1621 with text “Sitta Kodt Matz”. The limestone tomb is oldest remaining in Estonia.
References:Bomarsund fortress and garrison was built in 1832-1854 by Russian Empire to defence Åland Islands against enemies. British and French fleet attacked against it during the Crimean War in 1854. After a week of fighting the British stormed the remaining fort. Anglo-French forces destroyed it totally after battle. In the Treaty of Paris 1856, the entire Åland Islands were demilitarized, which is a status that has been preserved until this day.
Nowadays there are some ruins left and fortress area is open for visitors.
