Shoreline Detectives

Tori and Alex explore the coastal archaeology of Essex. They investigate the earthwork remains of a fort dating to the time when Henry VIII took England out of the European Catholic union. They pay their respects to some Thames sailing barges, now sunk in estuary mud, but once the glory of the east coast, and they find a First World War German U-boat stranded in a tiny creek.

Tori and the team visit Dorset where they reveal the story of the world's first aircraft carriers, they discover how this coastline played a vital role in D Day, and they search for a unique and huge Iron Age monument that can only be seen, sometimes, for a few hours a year.

In Glasgow, Tori explores the river Clyde, finding a strange vessel on the foreshore that was instrumental in helping to create the city. She discovers a wall that changed the city forever, and an intriguing wooden structure that gives a tantalizing glimpse into the world as it was on the River Clyde 2000 years ago.
