A complete, full-color cadastral map of the entire town of Biecz (Beitch, Beitsch, Baych, Baytsh, Beytch), surveyed and lithographed in 1850. This archive copy includes extensive redline revisions drafted over the 1850 original, apparently for an 1876 edition, covering not only the usual parcel and building changes but also a major re-routing of the Ropa River through town to accommodate the arrival of an important rail line; because this map includes both the original and modified landscapes, it captures a significant historical transformation of the town. The map also shows a well-formed market square, three churches and several Catholic cemeteries, a Jewish cemetery, a hospital, and several named hamlets. Images for this map were provided to Gesher Galicia by the Archiwum Państwowe w Przemyślu.
