Toppler Castle, Medieval château in Rothenburg ob der Tauber, Germany

Toppler Castle is a small late-medieval residential tower: a two-storey rubble-stone base 5.4 m in diameter carries two overhanging timber-framed storeys under a steep gabled roof. The stone section holds an arched wooden door with a small window above and three square reliefs in a row; the light blue plastered upper part, on dark wooden brackets, has two rows of dark-framed windows.

Heinrich Toppler, mayor of Rothenburg from 1373 to 1407 with interruptions, bought land outside the city and built the small moated castle between 1388 and 1390 as a summer residence. The purchase contract also bound it to protect the mills in the Tauber valley. After Toppler's arrest in 1408 it passed to the city, later to several Rothenburg families, and in 1861 to the Boas family.

This residence reflects the authority and wealth of the mayor who commissioned it, standing as a testament to civic power rather than nobility. Visitors notice how the tower dominates the valley below, embodying the political influence of Rothenburg's leadership during the medieval period.

The fortress sits below the city and is accessed via marked hiking trails through the valley, which require some climbing to reach the structure. Plan your visit when weather is favorable, as the pathways are steep and the walk involves a moderate physical effort.

The castle stood in an artificial pond up to 55 m across, fed by a spring and drained via the Fuchsmühle into the Mühlbach. A drawbridge once crossed it; a 16th-century stone bridge replaced it. The Duke of Saxe-Altenburg had the Herzogsstuhl built at his Rieseneck hunting lodge around 1900 on its model.
