Hof Neuroth, Water castle in Bilkheim, Germany

Hof Neuroth is a water castle near Bilkheim, its square plan formed by building over the courtyard of an earlier right-angled two-winged moated house. The yellow facade rises from a high basement to two full storeys, with four storeys in the tower, all under baroque mansard roofs with numerous dormers. A two-arched stone bridge on the northeast side leads to the entrance, whose front has five window axes.

The first predecessor was built shortly before 1340 as an allod of the Burgmann family von Neuroth. In 1584 it passed by inheritance to the von Brambach family, who united it with older estates. The date 1664 on the weathervane marks either the present building or a Baroque remodelling; the current form with its tower dates from an 1856–1858 rebuild under Carl Wilderich von Walderdorff. Johann Philipp von Brambach sold the castle to Wilhelm Reinhard Freiherr von Walderdorff in 1687 for 13,000 Rhenish guilders.

The name Neuroth comes from the Burgmann family von Neuroth, who held the estate before 1340; a related ministerial family of the same name had a farmstead elsewhere in the district before 1222. From the Brambach period onward, and under the Walderdorffs from the second half of the 19th century, the house served as a secondary residence; when no family member lived there, foresters and estate officials were housed in it, while tenants of the adjoining farm looked after the manor house.

The castle is private property of the Walderdorff family and can be viewed from outside. Visitors should observe the posted signs and keep distance from residential areas to respect the family's privacy.

The castle evolved from an original right-angled two-wing water fortress that was later transformed into its present square layout. This architectural change reflects how living needs and tastes shifted over the centuries.
