Spain's Hidden History

Christa Larwood is in Southern Spain exploring the hidden treasure buried beneath the living sand dunes along the Mediterranean coastline. The area was once home to a huge Roman settlement, and its remains are now surfacing. Cat Moh is in the UK's northernmost city Inverness, the gateway to the Scottish Highlands for our next instalment of Day Tripper. Plus, we head to Greenland, that's fast becoming a bucket-list destination for its rich culture and landscape.
