The Germans’ Gate from the 13th century is one of the last medieval bridge castles found in France. As a historic Garrison town, Metz has been heavily influenced by military architecture throughout its history. From ancient history to the present, the city has been successively fortified and modified to accommodate the troops stationed there. Defensive walls from classical antiquity to the 20th century are still visible today, incorporated into the design of public gardens along the Moselle and Seille rivers. A medieval bridge castle from the 13th century, named Germans’ Gate (French: Porte des Allemands), today converted into a convention and exhibition centre, has become one of the landmarks of the city. Today there was an art exhibition called Flash Mobile so we went to check it out.
