Dirnitz

A dirnitz (German: Dürnitz or Türnitz, from the Slavic dorniza = "heated parlour", Danish: Dørns, North Frisian: dörnsch or dörnsk[1][2]) or Knights' Hall was the heatable area of a medieval castle.

It was usually a single large room on the ground floor of the palas below the great hall.

Occasionally it also described the cabinet (Kemenate) or an entire hall building.

Typical examples of a dirnitz may be seen at the Wartburg and Heinfels Castle.

The dirnitz at Burghausen Castle is one of the rare examples where the heatable hall is on an upper storey.
