The construction of Sofia Albertina Church began in 1754 by the design of Carl Hårleman and it was inaugurated in 1788. It is named after the sister of Gustav III of Sweden. Sofia Albertina replaced the medieval church from the 1400s. The church has unusual design, because it has two towers but it's not a cathedral of bishop's seat.
The font dates from the 12th century. It was a used as a fountain in local family's garden until they noticed its value. Chandeliers were moved from the old church and they date from the 1600s.
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.
