Porto is Portugal’s second city, with the greater metropolitan area having a population of around 2.4 million. It sits in the north of the country on the estuary of the Douro River as it reaches the Atlantic Ocean. Its rich history dates back to Roman times, while visitors will also see evidence of Portugal’s ‘Age of Discovery’ when its explorers sailed to far-flung places. Porto is the birthplace of Dom Henrique, Duke of Viseu, better known as Henry the Navigator, who was central in developing the Portuguese Empire in the early 15th century. Porto’s historic centre was awarded UNESCO World Heritage status in 1996, and visitors will soon realise why as they begin to explore the city.
