In this three part series, writer and adventurer Will Millard discovers the hidden history of Wales by exploring forgotten, secret and usually inaccessible locations that show the country as you've never seen it before.

On an intriguing, exhilarating and sometimes dangerous journey, Hidden Wales with Will Millard offers unprecedented access to places you rarely get to see. Starting in the north and working his way south, Will reveals natural wonders hidden beneath the landscape, the abandoned buildings that tell us where Wales has come from and the modern marvels of engineering that show what the country might become.

In this second episode, Will continues his tour around Wales by moving to both mid-Wales and the west of the country. From a lead mine that's thousands of years old and a beautiful cave with a very scary entrance to an abandoned sea fort and a derelict mental asylum, Will uncovers historical gems that reveal parts of the middle and west of Wales that you never knew existed.
