1. The Trouble with Temples - Friars Wash, Hertfordshire

Time Team has never found a Roman temple. But a 30-year-old photograph clearly shows double square cropmarks in a field. Surely this time they will strike lucky? The trouble is, the site may have suffered plough damage. Francis takes charge. Though initial excavations are encouraging, John and Stewart are puzzled by a geophysical anomaly. Including a tessellated pavement and a coin hoard, a picture gradually emerges of not one but four temples - in fact a whole complex of buildings. It proves to be one of the most important excavations in Time Team history.
