The foundations of an ancient Roman crypt dating from the first centuries of our era was uncovered in 1978 in the central area of the Dax. After the archaeological excavations, an archaeological crypt was built under the building to keep the testimonies of the ancient city. Long considered the foundation of a temple, the remains are now interpreted by archaeologists as belonging to a civil basilica, public meeting place where many activities took place in civic life; made there including justice. Few basilicas are known in the Roman world to this day. The most important archaeological museum in the crypt are presented.
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.
