MAULEON FORTRESS - Was this fortress built by Alphonse "the Pugnacious", king of Pamplona and Aragon (from 1104 to 1134), at a time when Gassion, 4th viscount of Soule (from 1120 to 1130) strengthened his ties with Navarre ? Maybe, but there was certainly an earlier construction on the same spot belonging to the Viscounts of Soule (the first of whom was Guillaume-Fort, viscount 1023-1040). And it is equally likely that the Romans had built a stronghold (oppidum) on this high point of Mauléon and the Saison river valley... on top of a former « gaztelu », camp retranché protohistorique.
