Lisbon is the main port of Portugal, which is located at the mouth of the Tagus River. This city is located in the picturesque place with numerous hills. That’s why Lisbon is also called “city on seven hills”. Founded as a large settlement of the tribe of Iberian Lusitano, Lisbon has started its quick development due to its convenient location. After this it was soon conquered by the Roman Empire, then it belonged to the Arab Caliph, and later the French knights set up their ownership. Only in 1256 Lisbon has officially become the capital of Portugal. However, after a large earthquake that had destroyed many historic buildings, the city often became an arena for political clashes. Only the end of World War II has finally brought the city its long awaited peace.
