Altes Schloss Büdesheim, Renaissance castle in Büdesheim, Germany

Altes Schloss Büdesheim is a three-winged castle from the Renaissance period that encloses a southern inner courtyard. The eastern wing preserves an older core structure, while the western wing houses a chapel.

A water castle stood here between the fortifications of Windecken and Niederdorfelden; its builders are unknown. Around 1017 the site passed as a donation to Michelsberg Abbey in Bamberg, whose Benedictines turned it into a fortified farm, later called Bruderhof. In 1554 the abbey sold it to Johann Brendel von Homburg, who built the present castle around 1558 reusing older parts, hence the name Brendelstein. In 1569 it went to the Schütz von Holzhausen family, and in 1760 to Philipp Reinhard Freiherr von Edelsheim.

The name Brendelstein comes from the Friedberg burgrave Johann Brendel von Homburg, who had the present building erected around 1558; a reused coat-of-arms stone bearing that year is set into the east wing. The castle chapel occupies the southern part of the west wing. Since the Schöneck municipality took over the renovated complex, it has been used mainly for cultural purposes.

The building currently serves municipal functions and is partially accessible to visitors during specific occasions. Ongoing renovations including elevator installations are making all floors easier to reach for public activities and events.

A heraldic stone from 1558 on the east side displays the historical name Brendelstein and marks a specific ownership period. This artifact shows how the building carried different names across its long history.
