The names of the three Buchenau castles in use today (Spiegel-Schloss, Seckendorff-Schloss and Schenck-Schloss) come from the former and current owners.

When in 1629 the Fulda monastery abbot, Johann Bernhard Schenk zu Schweinsberg, wanted to reinstate the Catholic church constitution, the von Buchenau family protested and temporarily fled to Bad Hersfeld.

The court was under the rulership of the Fulda Abbey and included Buchenau, Bodes, Branders, Erdmannrode, Fischbach (Hauneck), Giesenhain and Soislieden.

Two wooden reliefs from an altar shrine, several grave monuments in the choir from the 16th to 19th centuries and the organ from 1787 are notable.

The sandstone portal bears the Alliance coat of arms from Buchenau and from Schenck zu Schweinsberg.

In order to stop the ongoing deterioration of the castle, structural measures are urgently required.

The castle was built and added to over several centuries and today offers a very mixed architectural style.
