Preliminary remark: The present holdings comprise the maps and plans which were stored separately from the files and documents in the archives of the manor Unterdeufstetten (Fichtenau, SHA). These are mainly printed maps that can be divided into two larger groups. Cards concerning the knighthood possession Unterdeufstetten are next to those which have a further frame of reference. The geographical horizon ranges from maps of the Swabian Albverein to railway maps of the German Reich and world maps. Among them is a special group of World War I maps owned by Friedrich von Praun, whose wife Irene had inherited the manor Unterdeufstetten from her father Erwin von Seckendorff ( 1923). The maps and plans run from 1764 to 1950. The present holdings comprise 56 archive units. It was developed by Gisela Scharlau and entered into the computer system.
