Once ringed by tall ramparts very probably dating from the beginning of the 13th century, successively raised and then destroyed as the centuries went by, the town of Jodoigne now only has partial remnants left, albeit quite extensive ones. These walls give us an idea of the more or less triangular shape of the fortifications, which once had eight or nine towers and several gates. The walls enclosed the old primitive castle built on the site of the current Pastur castle, the Grand-Place or Place du Marché and the mediaeval town, in particular leaving outside the walls the church of Saint-Médard, which itself is an exceptional heritage site of Wallonia.
The largest sections of the ramparts still preserved, located to the rear of n° 4 Rue Saint-Jean, include a semicircular tower and a relatively large portion of the walls. Other remnants of these fortifications built from various stone blocks and Gobertange stone meet to the rear of n° 13 Rue du Château, the rear of nos 1 to 11 Rue de la Grande Montagne and nos 8a, 9 et 10 Grand-Place (in the heart of the property of the Viscounty) as well as in Rue du Sergent Sortet at the rear of n° 25 or the old château Ghobert.
