The Catacombs of Marcellinus and Peter are ancient catacombs situated near the church of Santi Marcellino e Pietro ad Duas Lauros. Their name refers to the Christian martyrs Marcellinus and Peter who, according to tradition, were buried here, near the body of St. Tiburtius. In 2006, over a thousand skeletons were discovered in these catacombs; the skeletons were stacked one on top of each other and still bore the togas they were buried with.
The Catacombs are open only on Saturdays and on Sundays for individual visitors.
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.
