PAM – Provincial Archeological Museum
Based in the adjoining village of Ename (a 10-minute bus ride from the center), this interactive museum narrates the last 1,000 years of history in the region. Its sites sprawl a village that once stood on the border between medieval France and Germany. Visits include the open-air museum of the archaeological park, where you'll find the first stone inklings of a Benedictine abbey and the foundations of the old city that once stood here.
