below our present sea level. The valley was subsequently filled with boulder clay and gravel. The ice sheet, which produced the chalky boulder clay, rolled upon a bed of glacial sand and gravel, and formed the flattened character of the area today. The main river running through the country park is not the Stour. This is a mill stream called the 'new cut', established to operate a mill belonging to the priory, in use in the 14th century. It is joined at the eastern end of the country park by the Chilton stream. This itself is fed by the Hawedych, and by another stream coming down from Poslingford. The smaller Stour now runs south of the country park, meandering around the priory and meadows. History Prehistory Paleolithic implements were discovered within the Priory grounds. A Mesolithic quartzite pebble macehead was found in the same location. A Neolithic stone axe was retrieved from the River Stour; a polished flint axe in a gravel pit to the east and a flint head in a meadow just off the Ashen Road. A Neolithic flint arrowhead was found in a garden on Bridewell Street. A Neolithic long mortuary enclosure and three Bronze Age barrows were located across the river towards Ashen. Evidence of a barrow together with 200 worked flints were found near Chilton Street. A Bronze Age socketed gouge was unearthed from plough soil on the Common. There are some 24 other pre-Iron Age structures in the parishes around Clare which may be located via Google Maps. An Iron Age pot was found embedded in the river bank, half a mile east of Clare. Together with an iron spearhead, they are held in The Ancient House. Iron Age coins have also been found, one from the Belgic Trinovantes tribe. In 2009 during a recent rebuilding programme at Clare Community Primary School, postholes of a late Bronze/Early Iron Age structure were located, with an associated ring ditch. This supports the view that Clare Camp (OS TL768458, at the north end of the town, just behind Bridewell Street) with its double ditches, one of the most impressive of its kind in Suffolk, is from that period; with an area of 2.9 hectares, it is second only to Burgh Castle. It is now entered into the Atlas of Hillforts. The north side is most complete, with an inner rampart 9 ft high and counterscarps 12 and
