Pulverturm, Medieval defensive tower in Rottweil, Germany.

The Pulverturm is a powder tower in Rottweil's medieval fortification system, built with thick stone walls in a round shape. The structure sits integrated into the city's defensive network and defines the skyline with its sturdy, utilitarian form.

The tower's roof timbers were dated by dendrochronology to 1466/67, though the structure itself is probably older. From 1700 it served as the town's and the Swabian Circle's ammunition magazine, storing gunpowder made in the powder mill. Since 1912 the building has housed the Rottweil city archive.

The tower's name comes from its use from 1700 as the town's and the Swabian Circle's munitions magazine, storing gunpowder made in the local powder mill. Above the entrance a frieze reads "Der Vergangenheit zur Wehr, der Gegenwart zur Lehr", with Rottweil's coat of arms set in a medallion. Beside the tower stands the tomb of Dr. Vogel, a former town physician, from the years when the Bockshof served as a cemetery.

The tower stands in the Bockshof above the Neckar valley on the northeast side of the former town wall; the city archive has used the building since 1912, so it is not open as a lookout. The lower storey rests directly on solid rock, and the 1912 annex towards the Bockshof has a lean-to roof. Next to the tower stands the tomb of the former town physician Dr. Vogel.

The tower's roof beams were dated by dendrochronology to 1466/67, so the tower itself is probably older. Above the entrance a frieze reads "Der Vergangenheit zur Wehr, der Gegenwart zur Lehr", with Rottweil's coat of arms set in a medallion. Beside the tower stands the tomb of Dr. Vogel, a former city physician, from the time when the Bockshof served as a cemetery.
