Schloss Leonberg

Schloss Leonberg is a fortified castle overlooking the town on a hilltop, featuring rectangular towers and walls built across different periods. The structure combines Gothic defensive elements with Renaissance ornamental forms, and today sits adjacent to modern administrative buildings.

The castle was founded in 1248 by Count Ulrich I of Württemberg as a military stronghold. Between 1560 and 1565, Duke Christoph oversaw major renovations that transformed it into a more comfortable and representative residence.

The castle displays how medieval fortifications were gradually transformed into comfortable residences for nobility, a pattern visible across many German-speaking regions. Walking around the exterior, visitors can observe how rooms were modified over time to provide greater comfort and elegance.

The castle functions as a local government building and is closed to public interior visits. However, the exterior and grounds around the base are freely accessible, offering clear views of the towers and stonework.

In 1609, Duchess Sibylla, widow of Duke Frederick I, chose the castle as her personal residence. This decision marked a shift from a purely military installation to a noble dwelling with domestic character.
