Here are the details of maps for Devizes:
We have published three maps for Devizes. That for 1899 is double-sided to give good coverage of the town, including part of sheet 34.14, and extends west to include most of the canal locks. For 1922 we have covered the town in two maps, allowing fuller coverage to the east as well as longer introductory notes and extracts from a 1907 directory.
Sheet 34.13 covers the west of the town. Features include Devizes Castle, Assize Court, railway station, west part of Market Place, St Peter's church, Kennet & Avon Canal, flight of locks, Central Police Station, etc
