The explorer Will Millard looks at some of the lesser-known landmarks in the principality.

Exploring Wales may not sound that adventurous, but in this opening episode set in the north, Millard visits the world’s biggest abandoned slate mine, a decommissioned nuclear power station, and a Victorian invention lying on the seabed.

Hidden Wales with Will Millard is on BBC Four at 20.00.
