Epiacum Roman Fort, also known as Whitley Castle, stands at 330 meters (1,050 feet) above sea level, making it the highest stone-built Roman fort in Britain. Built in the early 2nd century AD in the South Tyne Valley three miles north of Alston, the fort housed approximately 500 soldiers and was likely constructed to control lead and silver mining operations and protect routes to the northern frontier. Unlike typical rectangular Roman forts, Epiacum's unique lozenge-shaped structure was deliberately adapted to fit the hillside topography. Considered exceptionally well-preserved, the fort is described as 'the best preserved Roman fort in the Roman Empire' and remains on open-access land with free visitation. Archaeological surveys have recovered substantial Roman pottery and artifacts from the site, providing valuable evidence of Roman military occupation and provincial infrastructure in Britain's northern borderlands.
