The paper deals with twenty-two economic and forest maps which were created for the Plzen branch. Using them we can get an idea about the Plzen demesne from the late 18th century till the mid-19th century; at that time no significant changes in land ownership of the town occurred. The set includes manuscript and coloured maps with German keys. Oftentimes they are in italics. We can distinguish two main topic-based groups. The first larger unit comprises maps created by the forester and the town surveyor Frantisek Emanuel Recht (MP 583/1-11 and probably MP 616) which were created during the 1820s. Their main purpose was to depict the ploughed territory, i.e. town plots adjoining private plots which were illegally used by owners of the private plots. This illegal occupation often applied to town forests the edges of which would be turned into fields or meadows. The second group comprises maps which were created while forester Frantisek Erazim Ullmann (MP 50, 52, 695, 857 and 865) was in office. They were created at the turn of the 19th century and were used in the process of forest systemization. Unlike Recht's maps, this group survived whole and shows all forests in the demesne. Other maps were used for example for planning of roads (MP 9, 59, 842) or were included in a larger map set (MP 138). Map MP 677 is an exception, since it is the only one which shows the whole Plzen demesne with all forests and villages as they appeared in 1842. The map set could become a very valuable source of information about the development of forest and agricultural units in Plzen demesne during the monitored period. We can find lots of village and place names some of which have been used till now. And last but not least, these maps can be used as an interesting insight into the property and legal relations at that time.
