Michael Portillo's journey continues in two cities. He begins in Aveiro, a city of canals and brightly decorated boats, renowned as the Portuguese Venice. He enjoys the local food and discovers a historic connection between the city's patron saint, Princess Joanna, and England's King Richard III. He then drive to one of the country's most important cities, Coimbra. Portugal's first capital in 1139, it was once the centre of a mighty Roman province.
