The church ruin at Rokoberget is the remains of a church dedicated to the archangel St. Michael. The church was built of stone and was sited at the top of the Rokoberget hill. St. Michael's church was first mentioned in a papal letter of 1254 and has been a wayside church, but historians disagree about whether the passers-by were pilgrims or Swedes on their way to the market at Hamar. The ruins, which are accessible to the public, are fenced in. A path down to the right behind the bell tower leads to a look-out point.
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.
