Lisbon

Lisbon serves as the capital and largest city of Portugal. As of 2025, its official city limits hold an estimated 658,236 residents, while the broader metropolitan area is home to about 3,353,000 people. Situated on the northern bank of the Tagus River, the city occupies the western part of the Iberian Peninsula. The western edge of its metro region, known as the Portuguese Riviera, includes Cabo da Roca, the westernmost point of continental Europe.

Among the world’s oldest cities, Lisbon is also the second-oldest European capital, surpassed only by Athens. Its history stretches back to pre-Celtic tribes, followed by Phoenician settlement and civilization. Under Julius Caesar, it became a Roman municipium called Felicitas Julia, appended to the older name Olisipo. After the Roman Empire fell, Germanic tribes—chiefly the Visigoths—ruled from the 5th century, until the Moors captured it in the 8th century. In 1147, Afonso Henriques took the city, and by 1255 it had replaced Coimbra as Portugal’s capital. Since then, Lisbon has remained the nation’s political, economic, and cultural hub.

As the political center, Lisbon houses the national government, the Assembly of the Republic, the Supreme Court of Justice, the Armed Forces, and the official residence of the head of state. It is also the focal point of Portuguese diplomacy, hosting ambassadors from 86 countries, plus representations from Taiwan and Palestine. The metropolitan area, extending beyond the city’s administrative borders, contains about 3.35 million people—roughly 28% of Portugal’s population. This makes it the third-largest metropolitan area on the Iberian Peninsula, after Madrid and Barcelona, and one of the ten most populous urban areas in the European Union.

Lisbon is classified as an alpha-level global city, recognized for its roles in finance, commerce, fashion, media, entertainment, arts, international trade, education, and tourism. Alongside Porto, it is one of only two Portuguese cities to hold this global-city status. The city hosts three companies from the Global 2000 list: EDP Group, Galp Energia, and Jerónimo Martins. Lisbon stands as a major European economic center, with a growing financial sector; the PSI-20 index is part of Euronext, the world’s largest center for debt and fund listings. The Lisbon region boasts the highest GDP PPP per capita in Portugal, at US$179 billion, or $61,713 per person. By gross earnings, it ranks as the 40th richest city globally, and most multinational corporations operating in Portugal base their headquarters in the Lisbon area.

The origin of the name “Lisbon” remains uncertain. It may derive from a Proto-Celtic or Celtic term such as Olisippo or Lissoppo, which later peoples—Phoenicians, Greeks, and Romans—adapted. Some classical writers like Strabo, Solinus, and Martianus Capella repeated legends that the mythical hero Ulysses (Odysseus) founded the city. The geographer Pomponius Mela, a native of Hispania, wrote it as Ulyssippo in Latin, while Pliny the Elder used “Olisippo,” and Greeks called it Olissipo or Olissipona. Another unsubstantiated claim suggests a Phoenician phrase Alis-Ubbo, meaning “safe harbor” or “pleasant haven,” but no ancient classical literature supports this folk etymology, despite archaeological evidence of Phoenician presence around 1000 BC. The city’s name is often abbreviated as “LX” or “Lx,” stemming from an old spelling, Lixbõa, though that spelling is no longer used.
