Much is made of the contrast and rivalry between Porto and Lisbon - 'Lisbon shows off, while Porto works' - and the two port cities are the centre of the urban and commercial life of the country. Giving its name to the nation, Porto dates from Roman times, prospering during the age of Portugal's overseas expansion as explorers and adventurers sailed to South America, Africa and Asia and its city merchants developed the lucrative wine trade with England in the seventeenth century. With a typical 'work hard, play hard' port atmosphere, Porto makes an excellent base to explore the beautiful Duoro valley. In the city itself attractions include the Praça da Liberdade, the fortress-like Sé cathedral and port tasting at the wine lodges south of the river in Vila Nova de Gaia. Porto enjoys some lively eating and drinking - the local delicacy is tripe - and you can sample 100s of varieties of port wine at the upmarket Solar do Vinho do Porto.
