The brick-made Joensuu Church was built in 1903 and designed by a Finnish church architect Josef Stenbäck. The church is in the Gothic Revival style, but it also has some features of Jugendstil. The high tower located in the southeast corner is the bell tower and in the lower southwest tower is the organ. It was built in 1969 by Organ Factory of Kangasala and has 36 stops. The church has 1000 seats. On the altar is a painting The Crucifixion of Jesus, made by Ilmari Launis in 1910.
References: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.
