Half-timbered houses â some with lurching walls and floors that arenât quite level â line many streets in the old city, rebuilt after a devastating fire in 1524. The best place for aimless ambling is the area bounded by (clockwise from the north) rue du GĂ©nĂ©ral de Gaulle, the HĂŽtel de Ville, rue GĂ©nĂ©ral Saussier and rue de la Pierre. Of special interest are (from southwest to northeast) rue de Vauluisant , rue de la TrinitĂ© , rue Champeaux and rue Paillot de Montabert .
