Manor in Porażyn, Palace in Porażyn, Poland

The Manor in Porażyn is a large residential building with rectangular form and a traditional pitched roof covered in tiles. Its solid masonry walls and small windows display durable craftsmanship, while the interior preserves old wooden beams and stone surfaces.

Built around 1880–1882 as the villa-palace Eichenhorst for Franz Heinrich von Beyme, owner of the Opalenica estates, it was designed by the Berlin firm of Hermann von der Hude and Julius Hennicke and published as a model in Architektonisches Skizzenbuch. It was rebuilt around 1900 and again during World War II. In 1920 General Kazimierz Sosnkowski bought the property as a residence; from 1 November 1945 it housed a forestry school, from 1971 the Policealne Studium Leśne, moved to Goraj in September 1993.

The name Eichenhorst, meaning "eagle's nest of oaks," was given to the villa built for Franz Heinrich von Beyme. From 1 November 1945 the palace housed a forestry school, and from 1971 a post-secondary forestry college until it moved to Goraj in 1993. Today the building serves as a training and leisure centre and hotel for the Grodzisk Forest District.

The palace stands in the part of Porażyn near the Porażyn railway stop, so it can be reached by train. The complex also includes a historic stable building and a forest park with beeches and oaks. The building now serves as a training and leisure centre and hotel.

The palace's name Eichenhorst means "eagle's nest of oaks", a reference to the surrounding oak forest. Its design by the Berlin firm von der Hude & Hennicke was published in Architektonisches Skizzenbuch as a model to imitate, praised for its composition and interior decoration.
