Written Scheme of Investigation Summary In August 2016 a trial trench evaluation was undertaken on a piece of land at the rear of 16 High Street, Mildenhall, Suffolk, prior to the construction of new dwellings. Two trenches were excavated within the footprint of the proposed development. The evaluation trenches revealed four phases of activity indicating the site has been in use throughout the medieval period from as early as the 12th century through to modern day. The medieval and early post medieval phases are characterised by a number of pits and postholes associated with the backyard activity of medieval properties. The later post-medieval activity is characterised by the remnants of small brick structures, including an oven.

Introduction In August 2016 Suffolk Archaeology CIC (SACIC) carried out an archaeological evaluation on a piece of land at the rear of the 16 High Street, Mildenhall, Suffolk. The project was commissioned by the client, Steve Watson, and undertaken according to a Brief (dated 12/07/2016) produced by the Archaeological Advisor (AA) to the Local Planning Authority (LPA), Abby Antrobus of Suffolk County Council Archaeological Service (SCCAS), and then addressed by a SACIC Written Scheme of Investigation (Gardiner, 2016; Appendix 7). This evaluation was required under the terms of the National Planning Policy Framework (NPPF), as a condition of planning permission for the development of the site. The relevant planning application reference is DC/15/1876/FUL. The proposed development consists of the construction of new dwellings. The site is located in the Forrest Heath district of Suffolk, in the civil parish of Mildenhall, centred on NGR TL 7100 7467. It is situated in the town centre and consists of a sub- rectangular area, equating 0.1 hectares, bounded by residential development on all sides (Fig. 1). 2. Geology and topography The bedrock geology is described as Holywell Nodular Chalk formation and New Pit Chalk formation, formed approximately 89-100 million years ago in the Cretaceous Period, in warm chalk seas with little sediment input from land (BGS, 2016). The site is flat and lies at an elevation of c.8.6m AOD. 1 3. Archaeology and historical background SCCAS have stated that the site requires archaeological evaluation as it lies in an area of archaeological importance recorded in the Suffolk County Council Historic Environment Record (HER). The site is located behind buildings that would have once fronted onto the medieval market place and in close proximity to the church in the core of historic Mildenhall. Earlier occupation evidence has also been identified in the vicinity of the site, at Recreation Way, with the discovery of large Iron Age enclosure ditches. The full results of a search of the Suffolk HER commissioned as part of the project (Ref No. 9190156) are included in the digital project archive. The table below summarises the HER entries within 500m of the site centre. HER No. Date Nature of Evidence MNL 617 Medieval The medieval historic core of Mildenhall. The site is located within the known boundaries of this area. MNL 329 Post-medieval The location of a post-medieval manor house with some modern alterations. Located 75m to the north of the site. MNL 695 Medieval An undated surface and a medieval posthole was found during monitoring works. Located 160m to the east-northeast of the site MNL 133 Medieval Market Cross, a scheduled monument with medieval origins. Located 60m to the east of the site. MNL 620 Post-medieval An evaluation showed a post-medieval 16th century pit and layers. Located 70m east of the site. MNL 680 Medieval A monitoring showed a late medieval to post-medieval ditch. Located 160m to the east of the site. MNL 746 Post-medieval Post Medieval structural features identified during evaluation trenching at 21 High Street, 100m southeast of the site. MNL 622 Iron Age Excavations at Recreation Way uncovered Iron age features including large ditches and habitation evidence.
