Tann Castle, built in the Renaissance and Baroque styles, is the ancestral seat of the Frankish noble family von der Tann and is still owned by the family today.
Today's palace complex goes back to a Niederungsburg built by Ministeriale in the 12th century. It developed from the 16th century when the three branches of the family began to expand and convert the Ganerbeburg into a castle. This resulted in three palace wings, the "Red", the "Blue" and the "Yellow Palace", which are almost completely grouped around an almost square palace courtyard (Wiki).
