Epiacum

Epiacum (also known in English as ‘Whitley Castle’) is a Roman fort built in the 2nd-century. It has several unusual features, including a lozenge instead of a rectangular shape and a series of dramatic banks and ditches along the sloping hillside.

It’s speculated that the fort was built as a defense for the nearby silver and lead mines, as well as providing support for the fortifications of Hadrian’s Wall.

The isolated site has been abandoned since the 4th century, and as a protected Scheduled Ancient Monument, the secrets beneath its earthen walls are only excavated by the moles that live in its grounds. These moles, which each can dig around 60 feet of tunnels a day, push shards of pottery, beads, and other artifacts to the surface, collected by volunteers in an annual molehill survey.

Since 2012, a not-for-profit company has developed a program of events at the site. Information can be found on their website.
