It is located in the parish of Preunschen in the municipality of Kirchzell, in the Lower Franconian district of Miltenberg in Bavaria.

The ruins of the hill castle lie on a northeast-projecting hill spur, the Schlossberg, at a height of 365.2 m above sea level (NN) above the valley of the Mud, three kilometres southeast of Kirchzell and only a few hundred metres northeast of the centre of Preunschen, about 13 kilometres southwest of the district town of Miltenberg.

The lords of Dürn, meritorious members of the retinue of the Hohenstaufen emperor and Schutzvögte of Amorbach Abbey, had the castle built sometime between 1180 and around 1200.

In 1337 Archbishop Henry reconciled with his cathedral chapter and signed over Wildenberg Castle to the canons for a short period.

In January that year Archbishop Gerlach enfeoffed the castle of Wildenburg, the town Amorbach and a free tenancy in Miltenberg, without the consent of his cathedral chapter, to Engelhard of Hirschhorn.

By 1810 the castle and the area around Amorbach became part of the Grand Duchy of Hesse-Darmstadt and, in 1816, was transferred to the Kingdom of Bavaria in an exchange of territory.

On the south side is a gate tower with a stepped portal and a castle chapel with bay window on the upper storey of the apse.

Its window arches on the upper floor, which are comparable to those of the imperial palace of Gelnhausen and Château de Guirbaden in Alsace, are of high artistic value.

Wolfram von Eschenbach may have written his description of the holy hill just based on contemporary paradise literature.
