Castell Cawr

Castell Cawr, or Tan-y-Gopa as it is known locally, is a heavily forested hill above the town of Abergele in Conwy county borough, Wales [1]. On it is found the Iron Age hillfort of Castell Cawr, which overlooks the River Clwyd [1]. The hill rises to 189 m (620 ft) above sea level [1]. Thomas Pennant visited the area in the 18th century, and noted the existence of the hillfort [1]. In 1860, James Halliwell-Phillipps wrote that the outline of the hillfort was obscured by vegetation, and identified the workings of a Roman lead mine on the hillside [1].
