Blick auf die Burgruine Scherenburg

The castle ruins of Scherenburg, also called Schloss Scherenberg, are the ruins of a hilltop castle (Hangburg) at 200 m above sea level. NN on a slope above the town center of Gemünden am Main in the Lower Franconian district of Main-Spessart in Bavaria.
The castle was probably built before 1243 by the Counts of Rieneck, who owned the land there, as a customs castle to secure their customs revenue when crossing the Main river and the borders to Würzburg. This led to disputes with the Würzburg Bishop Hermann I von Lobdeburg, who had the Slorburg built in the immediate vicinity in order to demonstrate his power here as well. In 1243 the disputes were settled by a settlement.
In 1469 the castle finally came to Würzburg and was given the name of Prince Bishop Rudolf II von Scherenberg and served as an official cellar until 1598 and was habitable until the 18th century. A wedding took place in the castle chapel in 1732.
In the second half of the 18th century the castle complex, which had been privately owned since 1825 and since 1965 the property of the town of Gemünden, began to deteriorate.
Since the 1990s, the Scherenburg Festival (open-air spectacle) has taken place in the courtyard of the castle ruins in summer.Source: de.wikipedia.org/wiki/Burruine_Scherenburg
