Petroplus, Waterston, Pembrokeshire 2003
This excavation was located around the medieval and later settlement of Newton, near Milford Haven, Pembrokeshire. It was undertaken in response the proposed development by Petroplus of Liquid Natural Gas storage tanks and associated groundworks, on the south side of the former Gulf oil refinery site.
The remains of Newton farmstead, the ancestral home of Sir Isaac Newton and demolished during refinery construction in the 1960s, were badly damaged and no further investigation was carried out. However, excavation close to these remains revealed a late medieval or early modern house, presumed to be the predecessor to the demolished farmstead, and a 16th – 17th century dovecote with underlying corn-drying kiln. A radiocarbon date of AD 720-960 was obtained from the kiln. Topsoil stripping in fields a little distance from the house revealed a roundhouse associated with three sherds of coarse pottery. Radiocarbon determinations from charcoal from roundhouse postholes give a date range from 1450 BC to 920 BC. Post-excavation work is currently underway, and includes palaeoenvironmental analyses and examination of the prehistoric and later pottery. The project is funded by Petroplus.
