Smallest town (Stadt) in Bavaria

Ornbau is the smallest (population) town in the German state of Bavaria. Its designation as a town dates back to medieval times because a wall and a moat surround the town.

Medieval town

The town wall and the church are approximately 700 years old. The wall, the bridge, and the original steeple are still standing and in good condition. The town lies near the Roman town of Gunzenhausen. Gunzenhausen was an outpost on the Roman Limes Line, one of the largest structures ever constructed by mankind. On the chimney of the "old schoolhouse" there are giant crane nests that have stood for centuries. They are a source of pride for the citizens of Ornbau.
