Between July and October 2018, Oxford Archaeology East (OA East) undertook an open area excavation within an area of land known as Lamp Hill, located approximately 600m south-east of the National Trust property at Wimpole Hall, Cambridgeshire. The total excavation area encompassed 1.6ha and was undertaken in advance of a new car park to service the property. Located on a ridge of higher ground, in a prominent position overlooking the Rhee valley, as well as Roman Ermine Street and Akeman Street, the earliest evidence for activity on the site - apart from a small assemblage of earlier flints - dated to the Late Iron Age. This comprised a sequence of small enclosures and linear boundaries on the upper reaches of the south-facing slope. To the north, the remains of up to five ring gullies, probably agricultural in function, survived on the plateau of Lamp Hill. New enclosures were constructed at the end of the 1st century BC and while the ditches made some reference to those of the previous phase, there was also a sense of rapid re-adjustment. This trend continued into the Latest Iron Age and Conquest period as the area encompassing the crest of Lamp Hill became dominated by a large, tri-partite 'Hilltop Enclosure'. The peak of activity occurred during the Conquest period (c.AD 43 - 80), when there was a final phase of expansion of the Hilltop Enclosures, marked by another realignment and re-cutting of boundaries and enclosures, coupled with a high volume of small finds, mostly metalwork. While there was a lack of roundhouses during the peak phases of activity, the amount of material culture (particularly evident from the pottery, fired clay and metalwork) found within the ditches of the enclosures was indicative of occupation. What is also clear from the date of much of the metalwork, coins and to an extent the pottery, is that activity declined in the decades following the conquest, a decline that may be associated with the Boudican uprising of AD 60/1. A significant assemblage of metalwork was recovered with a large proportion dated to the 1st century AD, although some items were residual in later features. Dominated by dress accessories, tools (mainly knives) and miscellaneous items, the best dating evidence is provided by a group of 19 Latest Iron Age brooches dating to c. AD 10-40/50, and a smaller group of six brooches introduced at the conquest, but with none later than c. AD 70. There was also an unusually large number (10 in total) of Late Iron A...
