Porte de Trèves
Originally constructed in the 14th century, Trier Gate is the last remaining evidence of the medieval city wall that once encircled Bastogne. The ramparts kept the city safe until 1688, when they were demolished on the orders of French king Louis XIV, and the gate was converted into a prison—a role it performed until 1914. The German offensive in 1944--45 almost destroyed the building, but it has since been restored. Today it occasionally hosts temporary exhibitions—you'll need an appointment to look inside at other times.
