A stroll will allow you to discover Gothic facades of the 15C and the 16C buildings. For example, Thomassin Mansion (Salengro Street) or Baressols Mansion, near the church but specially, 18C mansions like the ones of Lyautey of Colombe and Raillard of Granvelle (at Grand-Puits Sq.) or the Law Courts (Palais Sq.).
