Report on the excavation of two trial trenches, dug to inform the proposed widening of the A46 road between Lincoln and Newark. The trenches were located on either side of Folly Lane, adjacent to the A46 at Gallows Nooking Common, and were positioned across an intermittent low bank, which marked the Lincolnshire and Nottinghamshire county boundary in this area. It had been suggested that the bank had earlier origins, marking the original alignment of the Roman Fosse Way, although no trace of the former Roman road was identified in the trenches. The bank was shown to be badly disturbed, and although redeposited sherds of Iron Age, Roman, medieval and post-medieval pottery were recovered, it remains undated. Further ditches were identified running parallel to the bank, some stretches of which have been identified as post-medieval, and others being Iron Age in origin. It was suggested that the possible bank and ditch system perhaps represents a sequence of construction of territorial boundaries dating from the Iron Age to the Anglo-Saxon or medieval period, although this interpretation remains tentative.
