Castle Wild (Wildburg) lies southern behind the Castle Treis. It was built in the 13th or 14th century, probably as protection of the southern side of the castle Treis. In the fifties it was restored and made fit to live in. Back then, the northern situated, almost square, donjon was repaired and received a new roof. The great hall and other outbuildings were also rebuilt. Other buildings and the circular wall are just ruins. Wildburg is private property
