Considering the Tulip Inn Tournai in Tournai?

Le Pont des Trous by Mahieu
The Pont des Trous ( Bridge of Holes) is part of the medieval military heritage of Tournai. It is part of the citywall and was a good defense for the city. The towers of the bridge were built late 13th-beginning 14th century.
On top of the tower there's a terrace where you can enjoy a couple of drinks. Just make sure you get up at the left tower (coming from the small parc), if not you have to cross the whole river!
