The Gothic town hall of Arras and its belfry were constructed between 1463 and 1554 and had to be rebuilt in a slightly less grandiose style after World War I. The belfry is 75 meters high and used to serve as a watchtower. Nowadays tourists can enjoy ascending the belfry.
The belfry of the town hall is part of the UNESCO World Heritage site of The Belfries of Belgium and France (the group of 56 historical buildings).
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.
