Tournai Cathedral, also known as the Cathedral of Our Lady, is a Roman Catholic church in Tournai, Belgium. It is one of the most impressive examples of medieval architecture in the country, with construction beginning in the 12th century and continuing into the 14th century. The cathedral is known for its five massive bell towers and beautiful stained glass windows. It has been designated a UNESCO World Heritage Site.
The Tournai Cathedral is believed to be haunted by the spirits of former clergy and parishioners.

There are also accounts of the organ playing by itself and the sighting of a ghostly monk who wanders the halls at night.
