The site lies to the southern side of the A17 directly to the east of an existing warehouse, to the north-eastern edge of Newark-on-Trent. The wider development area covers an area of approximately 13ha, whilst the area earmarked for further archaeological investigation on the basis of the geophysical survey covered an area of approximately 2.7ha. The main part of the development area, and the specific area with which this report is primarily concerned, lies to the south of the A17 and comprises two arable fields separated by a track; this is part of the perimeter track associated with the former use of the site as the airfield for RAF Winthorpe. The presence of an established crop of elephant grass on the site inhibited the excavation of all nine proposed trenches during this stage of fieldwork. After discussion between representatives, it was decided that initially a single trench be opened to establish the nature of the preservation of archaeological deposits and to inform excavation strategies. Based on the results of the excavation of the single trench, it was agreed that subsequent excavation of two trenches would be undertaken. These trenches were targeted over anomalies identified in the geophysical survey. Overall, three trenches out of the proposed seven were excavated during this stage of works, each measured 50x2.1m. Due to the crop initially inhibiting access to locate the trench via GPS, the first single trench was set-out by hand-measurement from known boundaries from an accessible easement cut by a prior clearance event. Consequently, the trench had been moved approximately 15m to the south-east and 6m to the north from its original planned location. This trench was subsequently located via GPS. All subsequent trenches were subjected to a clearance event by the mechanical excavator to facilitate the positioning of the trench via GPS to their accurate locations. All trenches were excavated under constant archaeological supervision using a rubber-tracked 360˚ excavator fitted with a 2.1m wide ditching bucket. Where possible, to facilitate sequential backfilling, topsoil and subsoil were stored separately upon excavation. The evaluation uncovered extensive and complex archaeological remains across all three trenches, predominantly comprised of enclosure and boundary ditches. A total of 142 sherds (3.024kg) of pottery dated from the Late Iron Age to the later Romano-British periods were recovered from a range of features across all three trenches. Peak occupation of the site is suggested by the ceramic data of dating to the Later Roman period that perhaps may be tentatively linked to the Roman urban development of Crocolana, located c.3km to the north-east of the site. However, the interpretation of the site is tentative at this stage based on the small-excavated sample.
