The Trier Imperial Baths (Kaiserthermen) are a large Roman bath complex, designated as part of the UNESCO World Heritage Site. The impressive ruins of the baths, along with the derelict rooms and the walls of previous structures, are among the most important to have been discovered in Trier. Today a visit to the thermal baths, which can also be explored below ground, is like stepping back in time. The walls of the hot bath (caldarium) are deservedly part of this famous landmark in Trier. After the one in Rome, the Imperial Thermal Baths and St. Barbara Roman Baths were once among the largest bathing complexes in the Roman empire. They were built in the first and second centuries AD.
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.
