At the far end of the castle outbuildings, at the corner of this large brick tower, a few steps up an old staircase lead to the ancient ramparts. In the 11th century, the walls completely surrounded the small town to protect all the inhabitants from invaders. A sentry walk 5 to 6 metres wide allowed sentries to observe the surrounding area. Mortars and howitzers set up along the ramparts easily swept the whole valley. First of all, we pass the stele of the "Human Rights Route". In 1989, the non-profit organisation "Congrès de Polleur" created this "route", made up of 17 steles, each depicting an article from the Declaration of 1789. It should be noted that the one in Limbourg is not numbered because it lies outside the boundaries of the Marquisate of Franchimont.
