A Gemarkung (also Markung, in Switzerland also Gemarchen) is the entirety of all land plots of a specific municipality, or a specific large part of a municipality, recorded in the cadastre in the countries of Germany and Switzerland (For an equivalent concept in Austria and adjacent countries see Katastralgemeinde).
Gemarkung may be variously translated into English as: district,[1] cadastral district,[2][3] local subdistrict,[4] cadastral area,[5] tithing,[6] township,[6] parish,[7] section of a community area[8] Gemarkung registers record the parcels' location, usage and geomorphology and the like qualities, however, the rights to the land (as property, or collateral liened by a mortgage) are kept in the Grundbuch (land register).
A Gemarkung is made up of a number of, usually contiguous, plots of land/parcels (Flurstücke).
In many cases, several "Flurstücke" are grouped together to form a Flur, usually a tract of open land or forest.
In sum, the sequence of the three subdivisions is: Gemarkung - Flur - Flurstück.
