Morstein Castle, Medieval castle in Gerabronn, Germany.

Morstein Castle stands on a mountain spur above the Jagst valley, separated from the village by a neck ditch. A ring wall encloses the outer bailey and inner castle, which are linked by stone bridges; the inner bridge replaced a medieval drawbridge whose remains are still traceable. The core is dominated by a medieval keep of bossed ashlar and the Renaissance palas with a stepped gable.

The Lords of Morstein built this knightly fortress in the 13th century, which later passed to the Lords of Crailsheim through inheritance. This transfer of control shaped the castle's later development.

The castle transformed from a military stronghold into a Renaissance residence after a fire in 1571, reflecting how people's tastes changed over time. This shift is visible today in how medieval and early modern features exist side by side.

Access is via a stone bridge over the neck ditch, covered on the castle side by a half-timbered gate tower built in 1758. Behind it, a second stone bridge replaces the medieval drawbridge, whose remains are still traceable. The grounds lie on a narrow spur above the Jagst valley, so paths follow the wall line rather than a loop.

A round tower at the southern point secures the outer bailey and connects auxiliary buildings through stone walls. This layout demonstrates how the entire castle was designed as a unified defensive system.
