Fünfgratturm, Medieval tower in Augsburg, Germany

The Fünfgratturm is a four-sided stone tower in Augsburg with four small watchtowers perched on corbels at the upper levels and five pointed roof spirelets. The ground floor spans a vaulted interior, while the upper stories retain original wall frescoes.

The tower was built in 1454 as part of Augsburg's eastern fortification system around the Jakobervorstadt district. It became isolated after the city wall was demolished in 1867.

Locals call it the Fünffingerlesturm, the "five-finger tower", after the four small watchturrets on corbels plus the main tent roof, which together form five ridges. It is not the Fünffingerturm in Darmstadt. The turrets housed the Scharwächter, patrols who kept Augsburg's citizens sleeping soundly.

The tower stands isolated on the Jakobervorstadt side of Augsburg, and its exterior can be viewed at any time. The upper floors are reached by ladders and are open to the public only during events. The metal outside staircase of 2007/2008 is attached to the outer wall, not inside the tower.

The metal staircase added in 2007/2008 stands outside the tower, not inside, and was designed as a grid-like cage of metal bars whose outer dimensions echo the former city wall. Citizens protested the addition and launched a petition; on 3 April 2008 Augsburg's city council ruled it inadmissible, so the staircase stayed.
