The Church of the Three Crosses (Vuoksenniska chruch), designed by academician Alvar Aalto, is architecturally an interesting building. Its slender, high belfry describes a down shot arrow. Instead of the altar painting there are three crosses. Among the 103 windows only two are identical. Aalto planned the church also for other activities in the parish besides services. Therefore the church can be divided into three parts. In the church there are seats for 800 persons. The windows and lightning are high up, which creates fascinating display of light and shadow. The Church of the Three Crosses was completed in 1957. The stained glass on the ceiling is as old as the church and also designed by Alvar Aalto.
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.
