What defines a city? It may be the architecture, the people, its economic development or cultural preservation. It's very difficult to find all these at one place. However, Lisbon, the capital city of Portugal has a little of all the qualities that make up a great city. It is also one of the oldest cities in the European Union. #Lisbon went up nine places in the Telegraph Travel Awards to 26th in the category of World's Best Cities in 2016.
