Sandi Toksvig's Great Riviera Rail Trip | Preview (Channel 4)

Sandi takes a tour of iconic locations on the French coast, discovering the stories of monarchs, artists, and celebrities who transformed the region into a prestigious holiday destination.

She starts with a rail journey from Marseille to St Tropez. She taps into her inner Viking with a spot of sailing, hits the beach that launched a sexual revolution in the 1960s, and helps out in the vineyard with one of Provence's biodynamic winemakers.

Meanwhile, In Hidden Treasures, Sandi Toksvig meets Britain’s professional and amateur history hunters at four archaeological dig sites across the country to capture the stories of undiscovered treasures as they emerge from the ground for the first time in hundreds of years.

At each dig, Sandi is joined by archaeologist Raksha Dave who will work with the teams of experts excavating the land, as well as sharing the history of the biggest and most remarkable finds.

Sandi also searches for clues about the wider histories of the areas of each dig to answer questions the newly excavated items raise, as well as meeting local historians to help piece together the stories unearthed at each location.

Sandi Toksvig's Great Riviera Rail Trip begins Saturday 29th November at 8pm on Channel 4.
