The Pichl Castle was built up in the 16th Century by Georg Idungspeuger in its preserved form today instead of 1363 already mentioned in court Mitterndorf in Muerztal . The U-shaped building block has four projecting corner towers in the form of tent roofs. In the north -east tower, the star- ribbed domed chapel was previously housed. The ground floor has a paneled hall with a coffered ceiling. Also Johann Nepomuk Knights of Kalchberg was born ( 1765-1827 ) . He was considered the most important Austrian playwright Grillparzer ago and earned a historian and employee Archduke Johann's lasting contribution to the cultural life of Styria.
Today in Pichlschloss the Forestry Training Center of the National Chamber of Styria is housed .
