During the Second Margrave War in 1552, Forchheim was occupied by troops of Margrave of Culmbach and later expanded with new fortifications. The town's defenses were improved with bastions, towers, and gates. During the Thirty Years' War, Forchheim served as a strategic location and a refuge, and its fortifications were further developed. Various outworks and defensive structures were added, designed by prominent architects. In the 18th century, additional buildings were constructed in the town center. After changes in ownership, the fortress lost its military importance and was gradually demolished starting in 1875. However, the moats were transformed into a park for public enjoyment.

Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
