ROMAN VILLA AT DAN-Y-GRAIG HOUSE
Primary Reference Number (PRN) : 00218m Trust : Glamorgan Gwent Community : Porthcawl Unitary authority : Bridgend NGR : SS84037803 Site Type (preferred type first) : Roman Villa Status : listed building II, Scheduled Monument
Summary : Site of a Roman villa, partly excavated in the 19th century and surveyed by magnetometry and resistivity in 1989. Excavation revealed 8 phases of activity, mostly between the mid 3rd-mid 4thC, and survey showed the larger extent of the building complex.
Description : Villa site partly excavated in 1985-86 and surveyed by magnetometry and resistivity in 1989. Excavation revealed a sequence of 8 phases of activity, some quite minor; most of the activity took place between the mid 3rd century and the mid 4th century. The earliest features noted in the excavation was a post-hole structure or structures of indeterminate type and unknown date, possibly of more than one phase. The post-holes were overlain by patches of metalling, within one of which was part of a badly robbed rectangular building in coursed rubble laid with pink mortar, 7.70 wide and at least 6.22m long, and containing a T-shaped kiln which appears to have been used for drying corn or malting. Later features included a large void, a series of post-holes cut into the metalled surfaces and a boundary bank, followed in the 19th century by landscaping. The geophysical survey indicated that the excavated area formed part of a complex of masonry buildings of which the main range seems to have run at right-angles to the excavated building, possibly with other ranges or detached buildings to north and east. A winged corridor plan seems most likely. Finds recovered from the excavation, and from the site in the 19th century, included painted wall plaster, opus signinum and hexagonal roofing slates in Pennant sandstone. This appears to be a well-preserved Roman villa site consisting of a dwelling with agricultural processing structures. Roman villas are not common in Wales, and this particular example is likely to come under threat from development pressures. (Evans 2001)
