Mines royal company. Mind there is a problem with this. Neath Abbey was established in 1129 AD when Sir Richard de Granville gave 8,000 acres (32 km²) of his estate in Glamorgan, Wales to Savigniac monks from western Normandy. The first monks arrived in 1130. Following the assumption of the Savigniac order into the Cistercian order in 1147, Neath Abbey also became a Cistercian house. The abbey was ravaged by the Welsh uprisings of the 1200s, and eventually dissolved by King Henry VIII of England in 1539. At this time, the abbey was turned into a large estate. Sir Philip Hobby was the last occupant of the estate.
By 1730, some of the buildings were being used for copper smelting, and the rest were abandoned. In the late 18th century, an Iron Foundry was opened near the Abbey ruins by a company owned by the Price, Fox and Tregelles families.
The archaeology of the abbey was eventually excavated between 1924 and 1935. Source:Wiki
