Verdun-sur-Garonne

Verdun-sur-Garonne stands above the Garonne between Toulouse and the lower river. Its port was active from the twelfth century, when the river flowed close to the town walls. The castle and its unusual tower, square below and round above, overlooked this river settlement. Merchants and boatmen used the waterway to reach other towns, while the fortified centre served the surrounding countryside.
