Arras was founded on the hill of Baudimont by the Celtic tribe of the Atrebates, who named it Nemetacum or Nemetocena in reference to a nemeton (sacred grove) that probably existed there. It was later renamed Atrebatum by the Romans, under whom it became an important garrison town. The archaeological site Nemetacum in Arras is one of the rare sanctuaries devoted to the oriental god Attis in France.
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.
