Potsdam, enclosed by a town wall since 1733, was expanded by the “Soldier King” Frederick William I in the 18th century. Afterwards, the wall did not primarily serve as a defense wall, but rather as protection from smuggling and desertion of the town’s soldiers.

Demolished to a large extent in the early 19th century, the remains are now under a preservation order.

The wall was built from bricks covered with tiles. It consisted of strong pillars connected by arches. Restoration of the original outer appearance and protection from moisture played a key role during the renovation process.
