Ancient Rome By Train with Alice Roberts

Alice heads to Tarragona, once the capital of Iberian Rome, which boasts the largest Roman forum in the world and a vast amphitheatre unearthed below a church. In Cartagena, on Spain's south coast, Alice marvels at the area's subterranean riches and takes a skylift above the city to reflect on the many things her 1300-mile Roman odyssey has taught her.
