The Forum Baths are a ruin of a Roman bath complex in Augusta Treverorum, modern-day Trier. The site was converted in the 4th century CE from some older buildings, dated to around the 2nd century CE. The structure encompassed 8364 m2 The bath house utilized the passive heating of the sun, like many Roman baths, and oriented the caldarium and tepidarium to the south, and the frigidarium to the north.
Along with the other bathhouses, the Forum Baths remained in use through the end of the fourth century. But the complex fell out of use during the early fifth century as Trier was repeatedly sacked during the Migration Period.
In the 13th century, the remains of the bath began being used as a quarry for local buildings. In the 17th and 18th centuries, the Capuchin Order built some of the buildings for their monastery over the eastern part of the bathhouse. In 1802, the monastery was dissolved and nine years later, in 1811, the garden was transformed into a cattle market (German: Viehmarkt), from which the ruins get their name.
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.
