BRITAIN’S ANCIENT TRACKS… | Channel 4 7PM

Tony Robinson’s latest wander takes him to the Derbyshire Portway in the Peak District, which is believed to date back to the Bronze Age and boasts some of the county’s most spectacular views. There are plenty of interesting sights and artefacts waiting for him along the way, as Tony gets up close and personal with a prehistoric shark tooth, explores the secrets of an abandoned railway tunnel, and visits the mountain retreat favoured by DH Lawrence.
