The aim of the proposed paper is to look at the issue of broadly understood space through the prism of late medieval court books from Łęczyca (land and town records). Among the numerous issues included in them, a lot of space was also devoted to territory, which is the subject of concern for landowners. This care was expressed in matters related to the demarcation of, for example, individual settlements or parts of villages. Judicial sources also contain information about land measurements and mentions of material markers of space, i.e. boundary mounds, which were sometimes damaged as a result of incursions of some kind. Therefore, the following aspects related to space will remain in the speaker's sphere of interest: taking care of the area (setting boundaries, land measurement) and space violations. The paper will also attempt to statistically compare the discussed matters against the background of other entries entered into the books in selected years.
