Lisbon — Capital of Portugal

Lisbon (population 550,000 city; 2.9 million metro) is the capital and largest city of Portugal, and the westernmost capital city in continental Europe. Perched on seven hills above the Tagus (Tejo) estuary, Lisbon has been continuously inhabited for over 3,000 years — Phoenicians, Romans, Visigoths, and Moors all left their mark before the city became the capital of the newly founded Kingdom of Portugal in the 12th century.

Lisbon's greatest era came during the Age of Discovery (15th–16th centuries), when Portuguese explorers sailed from here to reach India, Brazil, and the Far East, building one of history's first global empires. Vasco da Gama departed from Lisbon in 1497 to reach India by sea. The city's wealth from trade financed the Manueline architectural style — a uniquely Portuguese blend of Gothic and maritime motifs seen in the Jerónimos Monastery and the Tower of Belém, both UNESCO World Heritage Sites.

The Great Lisbon Earthquake of 1755 — one of the deadliest in European history, killing 30,000–60,000 people and triggering a tsunami and fires — destroyed most of the medieval city. The Marquis of Pombal led the rebuilding, creating the grid-planned Baixa district that defines central Lisbon today. The city is also famous for fado music, its traditional yellow trams, and the Alfama district — a surviving remnant of Moorish Lisbon.
