In the 16th century, fires were even lit to make it easier to obtain building materials.

The first medieval estate was built in the area of the village church, but no traces of it can be found today.

The subsequent building was erected on the Hofberg, where archaeological excavations (2003 and 2005) brought fragments of the wall to light.

In the second half of the 11th century, Rappoto von Julbach was commissioned by the nobility to complete the Frankenburg fortress.

The Frankenburg was largely made of wood, but finds show that it was not completely wooden.

During the first expansion phase, the people of Julbach forced the unfree peasants around the Frankenburg castle to perform bonded labour.

The region belonged to the bishopric of Bamberg (Bavaria), which disapproved of the exploitation of the settlers' property.

In a letters patent, Emperor Frederick Barbarossa officially confirmed the 'fortress' of Frankenburg and its goods to his successor.

The emperor's demand in the same document that he be given a say in the allocation of bailiwicks also increased the political significance of the castle.

[2] A decade later (1170), Engelschalk von Reit handed over Zwispallen and with it the castle to Asbach Abbey.

These included piles of medieval nails, which indicate the presence of wooden structures at this location.

Instruments of this type are not usually preserved, but this broken piece can still be used to elicit sounds today.

Collections of old oven tiles were found in two different places, including one decorated with a winged griffin from the 15th century, together with charred animal bones.

These ovens were either used as a cooking area or the castle inhabitants threw rubbish into the fire.
