Trial trenching at Turweston located in Buckinghamshire was carried out between November 21st and December 18th 2019. at A total of 56 trenches were excavated representing 3% sample of the main site area. Trenches were positioned to avoid identified constrains and target both blank land and anomalies identified from a previous remote sensing survey and a geophysical survey carried out in 2013 and 2017/18 respectively. Furrow formations and a number of anomalies of likely archaeological significance were indicated from these earlier investigations. The archaeological features identified during this evaluation were dominated by agricultural furrows in the south of the site, these respected existing field boundaries but it was not able to assign a date to these furrows. Four pits were also identified in south, these contained 13 natural, and two artefactual, lithic flakes and possibly represent prehistoric waste pits. A pit and linear feature in Trench 7 produced a total of 42 pieces of Roman pottery dated to between 2nd-4th century AD. It is possible that the linear could form part of a structure or a possible drain associated with an unidentified structure. Trench 31B revealed a number of pits, one returned a minute fragment of post-medieval oxidised ware, a second pit also contained a sherd of post medieval pottery, whilst a third pit contained a sherd of medieval pottery.
