The Team visit Portsmouth to try and uncover one of the city's oldest buildings - a medieval hospital. But after three days of bone-chilling weather and confusing archaeology can the Team work out what stood on Governor's Green over 500 years ago? The Governor's Green is an historic part of the ancient city of Portsmouth. Before the Governors house was built in the 18th century a series of churches and pilgrims hospitals were on the site. And this is what Time Team wants to explore.
