The ground floor of the former town hall at number 30 houses a model of the town of Limbourg in 1632. Various exhibitions are held upstairs during the summer season. This building was constructed between 1681 and 1687 to replace the old market hall in the middle of the square (where the fountain with the Virgin Mary stands). It was used for meetings of the "States of the Duchy" and until 1703 for the high court and the feudal chamber. The town magistrate also had a room here.The old market hall shown on the model was demolished by the French army in 1675. In its turret was the communal bell "La Ridaine", which was transferred with the old public clock to the church tower. It disappeared in 1794 during the French Revolution. An enormous armorial stone reproducing an ancient town seal bearing the inscription "Sigillum Ville Lemborgensi(s)" is set into the base wall of the façade. This stone comes from the old building. The town's coat of arms can be seen at the top of the façade. Passing under the Arvo, you can see a coat of arms representing the cross of Burgundy with the year 1681.
