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:The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
