Eglwys Nynnid Farm, Water Street, Margam, Neath and Port Talbot
SS 8033 8480; Peter Boyer; Evaluation and Watching Brief; 13th - 31st March 2000 and September 2000 - May 2001; CgMs on behalf of Llanmoor Homes; ENF00
The first phase of the work consisted of five trial trenches, followed by the investigation of service trenches. Brownish orange, sandy clay silt glacial tilt was observed at between 18.78m OD and 24.14m OD.
A high concentration of archaeological features were exposed to the N of Eglwys Nynnid Farm complex. This included intercutting ditches, pits, postholes and a possible stone floor of a circular building. No discernible pattern was visible despite numerous postholes and no dating evidence was recovered. However they probably represented the remains of some post-agricultural buildings. A possible roadway or track consisting of a broken stone surface running N to S was possibly of Medieval or earlier date based on one pot-sherd.
To the S of the site, a small linear E-W ditch which may have served as a boundary feature for what is possibly a small apsidal-ended building also aligned E-W. This comprised a stone-lined foundation cut surrounding a broken stone surface. A possible post-built adjoining structure was suggested by two lines of postholes to the W. Associated with this structure were two possible burials and a possible timber framed structure to the W. The full extent of the structure was not revealed so their function was difficult to ascertain though a small chapel or church could not be ruled out.
In the E of the site, two leats were observed in plan and section probably feeding water to the Post-medieval water mill located to the SW of the site.
