The Uskela parish is one of the oldest parishes in Finland. Documents mention it for the first time in 1329. The church hill of Uskela is an old location for the church, with a church at this location since 1440. The small medieval stone chapel, dedicated to St. Anna, was dismantled in 1830.
The present church was completed in 1832. IIt was designed by famous architect C. L. Engel. The The belfry was erected in 1860. Inside the church the altarpiece was painted in 1849 by R. W. Ekman. The church has been renovated four times.
Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
