Schloss Philippseich, Historic château in Götzenhain, Germany.

Schloss Philippseich is a castle complex near Götzenhain, consisting of a plain mansard-roofed main building erected between 1794 and 1800 under Count Heinrich-Ferdinand, surrounded by numerous outbuildings and an 18th-century park. Among the outbuildings are the Grüne Bau, the administrator's house and a tithe barn. A cellar vault from the original 17th-century hunting lodge survives beneath a half-timbered house known as the Bunkerhaus.

Around 1675 Count Johann Ludwig von Isenburg had a two-storey wooden hunting lodge built in the family's deer park. His son Johann Philipp added the Grüne Bau and the castle church, which became the family crypt; after Johann Philipp's death the Isenburg-Philippseich branch was founded in 1711, making Philippseich the residence of a sub-county that included Götzenhain, Offenthal, Sprendlingen, Urberach, Messel and Münster until 1806. Between 1794 and 1800 Count Heinrich-Ferdinand built a new, plain mansard-roofed castle. The line died out in 1920 and the property passed to Isenburg-Birstein; in 1941 it left the family, and in the later 20th century it was thoroughly restored.

The castle church, built under Count Johann Philipp in the early 18th century, holds the family crypt of the Isenburg-Philippseich line. In summer it is used for services and weddings, and the Protestant congregation has a right of way across the grounds to reach it.

The grounds cannot be entered except during services of the Protestant congregation, which holds a right of way to the castle church; the church is used for services and weddings in summer. The castle itself now contains apartments, so there is no interior visit. The site lies near Dreieich-Götzenhain in the Offenbach district.

Before the castle changed ownership in 1941, its rooms held a notable art collection featuring family portraits, engravings of Hayn Castle, and English copper prints. Renaissance ivory sculptures were also part of this assemblage, reflecting the refined tastes of those who lived there.
