Report on the excavation of a single trial trench, dug in 'Bettie's Garden', forming land to the rear of 4 Cromwell View, Caistor. The trench was dug as part of a community research project, investigating the extent of the Roman walled town of Caistor. The investigation recorded modern rubble spreads containing small quantities of redeposited late post-medieval artefacts. The excavations were stopped before they extended beyond a deep layer of likely late post-medieval imported horticultural soil, however, and no significant archaeological features or deposits were therefore encountered.
