The report describes the findings of an archaeological watching brief carried out during improvements to the Market Square, Newark during the period 9th August 1999 to 18th October 1999, for the installation of 14 new lighting columns. The earliest phase of activity across the majority of the site was represented by dark grey silt/sand deposits. No dateable artefacts were retrieved from the deposit but it is suggested that this level could date to the late Medieval and/or early Post-Medieval periods (c.15th-17th centuries). A possible metalled surface in one lighting pit to the north of the Market Place may belong to the same broad phase of activity and could relate to one of two phases of metalling identified during an earlier evaluation of the site. Probable dumped or ground-raising deposits across most of the site preceded the laying of a surface comprising fragments of blue lias stone. This surface apears to extend across the majority or even the entire site and may be interpreted as an earlier market surface. In the absence of associated artefactual material, the surface could not be dated, but a Post-Medieval or more recent date would appear to be most likely in view of its relatively shallow depth. Probable Post-Medieval and/or modern dumps then occupy the upper levels of stratigraphy between the stone surface and the reinforced concrete base.
