Heiligkreuz, Kr. Bad Kissingen, Bayern

In the 17th century, Heiligkreuz was located in Niederfranken (Lower-Franconia, today northwest Bavaria) in an area called Dienheim, a cluster of about 15 villages owned by the Franconian Knights and in the possession of the Counts of Thüngen. On 28 June 1814, following the Napoleonic Wars, these Thüngen territories were awarded to the Kingdom of Bavaria. Heiligkreuz is located north of Würzburg.

Today, Heiligkreuz is administratively part of the municipality of Wartmannsroth.
