Kastenturm

Kastenturm stands beside the Heilig-Geist-Spital at Augsburg’s Rotes Tor waterworks. Its late-medieval defensive base supports two hexagonal storeys added in 1599. A stone balustrade has crowned the roof since 1703, overlooking three water towers and an aqueduct.

Water wheels once lifted water through this ensemble, which supplied Augsburg’s three grand fountains. The Rotes Tor system served as the city’s main drinking-water source until 1879. Pipes carried water from the tower towards public fountains and later private homes. Together, the buildings form part of Augsburg’s UNESCO-recognised historic water-management system.

Inside, Caspar Walter built a double-spiral wooden staircase in the sixth storey in 1742. Two people can climb separate spirals while holding hands through a slot in the central column. A pine cone crowns that column, while the former seventh-storey basin has disappeared. The Brunnenjüngling statue once stood there before moving to the Maximilianmuseum, where its grey-green patina remains visible.
