As an inscription plaque on the gate passage testifies, the “Schlettensche Kemenate” was built on the site of today's New Town Hall in 1590 by Christoph von Schletten and his wife Maria von Erthal. In 1634 the complex became the property of the Heußlein von Eußenheim family. Heinrich Christoph Heußlein von Eußenheim (May 2, 1656 - August 31, 1719) commissioned architect Johann Dientzenhofer to build Heußlein Castle in 1707 because the “Schlettensche Kemenate” no longer met his requirements. At that time, his family had a residence that has since disappeared, roughly at the current location of the Wahler'schen brewery on Bachstrasse near the Heussleinschen Hof. Heinrich Christoph Heußlein von Eußenheim most likely turned to Dientzenhofer on the recommendation or perhaps even through the mediation of his cousin Heinrich Freiherr von und zu der Tann.

In addition to the Ullstadt palace complex designed by Dientzenhofer, the palace built for the Heußlein von Eußenheim family is the only project by the master builder for which designs on such an extensive scale have been handed down. Dietzenhofer's designs can be divided into three stages: the "initial project", the "approved project" and the "improved project". The “initial project” includes an “elevation to the main facade”, a “floor plan to the first floor” and a “floor plan to the second floor”. In the second draft, the “approved project”, the floor plans for the two floors differ most clearly from the first draft, the “initial project”, in that the main front is extended by five axes. In the third draft, the “improved project”, weaknesses in the planning of the second floor were corrected compared to the “approved project”.

In the 1860s, castle lord Philipp von Heußlein reported a ghostly apparition in the castle. At the same time, the Kissinger Marienkapelle, in whose chapel cemetery the family's crypt was built, was said to have been brightly lit for three nights. ......
