Schloss, Architectural heritage monument in Maroldsweisach, Germany.

Schloss Birkenfeld is a three-storey main house built from 1738 on the foundations of an earlier water castle, whose slightly irregular ground plan still shows through. Bossed corner pilasters and a slightly projecting central risalit with a flat triangular gable articulate the facade. Four wings with hipped roofs group around a tiny light well and the main staircase, which has its own roof. Single-storey service buildings flank the cour d'honneur, closed off by two-storey pavilions.

The estate passed from the Zollner family around 1350 to the von Hutten, whose last male heir, Johann Philipp Friedrich von Hutten, began the present palace in 1738; interior work finished in 1775. The near-square core castle with two corner towers was replaced around 1742 by the new manor house, and the old farm buildings were rebuilt by about 1752. The counts of Ortenburg inherited the estate in the 19th century and still own it.

The interior decoration of the 18th century survives largely intact. Stucco work was done in three phases: Carlo Galdini in 1741/42, Johann Jakob Berg from 1752 to 1754, and the rich Rococo stucco of the upper floors by local master Bernhard Hellmuth. The wall and ceiling frescoes are by Johann Franz Gout; the "Italian" dining room was painted entirely al fresco with scenes from Greek mythology, such as Mercury and Argus and Apollo and Daphne.

Schloss Birkenfeld stands in the hamlet of Birkenfeld, part of the market of Maroldsweisach, not in Maroldsweisach itself. The estate is reached from the road through a gateway flanked by lions on sandstone pillars. The complex is privately owned by the counts of Ortenburg, so visitors should view the buildings from outside.

The main building had to be structurally secured between 1994 and 1997 because of construction faults dating from its building period, which the sources link to the involvement of a committee of noble "gentleman architects" advising the builder Johann Philipp Friedrich von Hutten.
