The Holy Spirit (Helgeand) Church, sometimes incorrectly mentioned as St. James, was built in the early 1200s. It was probably constructed as a chapel for the Danish Guild and donated by the Danish King Valdemar. In the mid-1200s the guild lost its importance and the church was sacrified as Holy Spirit Church and it also functioned as a sanctuary. The church is octagonal and built on two floors. Both floors have a common choir.
The original central tower collapsed around 1365 and Johannes van Wese donated 100 mark to the reconstruction. The church was was destroyed by fire in 1611. The church ruins are open to visitors in summer season.
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.
