Schloss Oberrain, Unken, Protected château in Unken, Austria.

Schloss Oberrain is a three-storey building with a hipped roof, its south façade divided by a tower two window axes wide. The top floor holds an open loggia with a double arch on a central column, and the windows carry stucco ornament that varies from storey to storey. A banded cornice runs across the walls, and a terrace on the north side leads into a garden.

The property originally developed as Seidlgut and later merged with a tavern under Konrad Leyrer's ownership, remaining within his family for roughly 200 years. During the 20th century, it served as a maternity home in 1940 and subsequently functioned as a command post for the US Army.

The building began as the Seidlgut farm and a separate tavern; the tavern's licence to serve drinks was first held by the Seidlgut and only later transferred to the tavern. The two were reunited under Konrad Leyrer, landlord at Unken, and the property stayed with his family for about 200 years.

The castle is located at Unken 8 and currently operates under anderskompetent GmbH, an organization preparing young people with disabilities for independent living and employment. Visitors should know that the building remains an active workplace and does not function as a regular tourist attraction.

Until 1830 the country road ran between the farm building and the tavern; the farm has since disappeared, leaving only the tavern wing in its 1891 remodelled form. The main building is three storeys high under a hipped roof, with a two-window-axis tower breaking the south façade.
