If you want to see the most impressive defensive structure of the medieval city of Metz, be sure to visit the Germans' Gate (Porte des Allemands). This unique monument of military architecture in France is a veritable castle-fortress spanning directly over the Seille River. The structure consists of two pairs of massive towers connected by a fortified bridge and served for a long time as the city's main eastern entrance.

The unusual name, Germans' Gate, was not given because of any German ownership, but rather due to its proximity to the hospital of the Teutonic Knights that was once located nearby. Although the hospital itself was destroyed back in the 16th century, the name stuck to this majestic outpost, which is now part of a seven-kilometer ring of preserved city fortifications.
This site is remarkable because it allows you to trace the evolution of military architecture: from elegant 13th-century pointed arches to massive walls several meters thick capable of withstanding heavy artillery. Today, the gate is recognized as one of the main architectural landmarks of the historical center and a must-see on any tourist's itinerary.
