Outer ward

Schaffhausen greatly expanded its fortifications

In response to the rising use of firearms, Schaffhausen greatly expanded its fortifications in the 15 th century. The Annot, the predecessor to the Munot, and its walls were reinforced with outer wards. These wards were later adopted in the construction of the Munot (1564–1589).

The Zwinger (Middle High German twingen = to force) was a stretch of wall running parallel to the city wall, which was backfilled with earth and equipped with projecting, semi-circular towers at regular intervals, like the example still preserved here.

The defenders reached the base of the tower via a sandstone staircase (now reconstructed) in order to be able to fire on advancing enemies from the side. Another defensive platform was originally located at the top of the tower.
