Roman-era artefacts are rare in Retford, although 1st–2nd century items were found at a site on Carolgate in 1922. The remains of a group of 1st–3rd century buildings were found at Babworth in 1981. A coin hoard was found at Little Morton that was dated to the 3rd century, and Roman artefacts and pottery fragments have been found at Tiln (Stroud, 2001). Evidence of Roman field patterns were identified by Derrick Riley of Sheffield University in the 1970s and 80s. Nottingham University archaeological researchers have said that during the 5th century and even into the 6th century, North Nottinghamshire was likely populated by "British communities with a sub-Romano-British culture".
