Burg Müneck, Medieval castle ruins in Breitenholz, Germany

Burg Müneck consists of castle ruins perched on a 543-meter-high hill at the southern edge of Schönbuch forest near Breitenholz. The remains display a deep moat and defensive earthworks that outline the site's original fortification system.

The first written mention dates to 1259, when Knight Hugo von Müneck, a vassal of Count Rudolf of Tübingen, sold a farm to Kilchberg Monastery. This early reference shows the castle was already functioning as the seat of a local noble power in the 13th century.

The name was first recorded in 1270 as Mugineke, with variants such as Mu(e)ienegge (1293) and Mönegge (1301); the element -eck refers to the castle's hilltop position, while Mugin- remains unexplained. Seals from 1301, 1307 and 1330 show the Lords of Müneck's arms as three or four points facing right or left.

A steep footpath leads up from Breitenholz to the ruins, or visitors can take a gentler route that begins at the adventure playground nearby. These different approaches let visitors choose a path that suits their fitness level and preferences.

Archaeological excavations in 1924 led by castle researcher Konrad Albert Koch uncovered the original layout and defensive structures of the site. This scientific investigation deepened understanding of how the medieval fortress was designed and fortified.
