Lisbon, officially the Very Noble and Ever Loyal City of Lisbon, is the capital and most populous municipality of Portugal, with an estimated population of 575,739, as of 2024, within its administrative limits and 3,028,000 within the metropolis, as of 2025. Lisbon is mainland Europe's westernmost capital city (second overall after Reykjavík), and the only one along the Atlantic coast, the others (Reykjavík and Dublin) being on islands. The city lies in the western portion of the Iberian Peninsula, on the northern shore of the River Tagus. The western portion of its metro area, the Portuguese Riviera, hosts the westernmost point of Continental Europe, culminating at Cabo da Roca.
Lisbon is one of the oldest cities in the world and the second-oldest European capital city (after Athens), predating other modern European capitals by centuries. Settled by pre-Celtic tribes and later founded and civilized by the Phoenicians, Julius Caesar made it a municipium called Felicitas Julia, adding the term to the name Olissipo. After the fall of the Roman Empire, it was ruled by a series of Germanic tribes from the 5th century, most notably the Visigoths. Later it was captured by the Moors in the 8th century. In 1147, Afonso Henriques conquered the city and in 1255, it became Portugal's capital, replacing Coimbra. It has since been the political, economic, and cultural centre of the country.
