The belfry of Tournai, Belgium, is a freestanding bell tower of medieval origin, 72 metres in height with a 256-step stairway. This landmark building is one of a set of belfries of Belgium and France registered on the UNESCO World Heritage List in recognition of their civic architecture and importance in the rise of municipal power in Europe.Construction of the belfry began around 1188 when King Philip Augustus of France granted Tournai its town charter, conferring among other privileges the right to mount a communal bell to ring out signals to the townsfolk.
The tower in its original form was evocative of the feudal keep, with a square cross section and crenelated parapet. It served in part as a watchtower for spotting fires and enemies.
