Bodenhof Castle, château in Sankt Stefan im Gailtal, Austria

Bodenhof Castle is a two-storey building with an attic storey and an irregular ground plan, its oldest parts from the early 16th century. The west portal and windows are Baroque, while the eastern half retains a late Gothic shoulder-arch portal and window frames. A polygonal tower in the southeast corner, with late Gothic pointed-arch windows, rises one storey above the rest; the north tower was built in 1927. A red marble fountain on the south outer wall is dated 1633.

In 1501 King Maximilian granted Bodenhof as a fief to Christoph Viertaler of Graz, who had received the Aichelburg a year earlier and was ennobled as "von Aichelburg" in 1507, founding that family; Bodenhof remains in the family's possession. The oldest parts date from the early 16th century. A restoration is recorded for 1644, a historicising remodelling between 1890 and 1910, and a general renovation between 1920 and 1930; the north tower was built in 1927.

The castle chapel, housed in the base of the southeast tower, is dedicated to the Three Kings and Saint Anthony; a building inscription at the entrance dates it to 1479. It spans two storeys as a two-bay room with a three-eighth closure and a late Gothic sacrament niche. The Neo-Gothic paintings above the altar showing the Baptism and the Birth of Christ are attributed to Johann Martin Schmidt.

The castle stands right by the St. Stefan-Vorderberg railway stop in the municipality of Sankt Stefan im Gailtal, so it can be reached by train as well as by car or bike. The grounds are privately owned by the Aichelburg family, so visits are not a given; ask locally before planning a stop.

A Late Iron Age bronze arm ring was found in the castle courtyard, evidence of a La Tène-period presence on the site long before the oldest building parts of the early 16th century. The object is the only prehistoric find recorded from Bodenhof in the sources.
