Lisbon

• 1. Introduction

  ›

  Lisbon is the only European capital older than every modern rival but one, and that one is Athens. Pre-Celtic tribes settled it. Phoenicians founded and civilised it. Julius Caesar made it a municipium and called it Felicitas Julia, grafting the title onto an older name, Olisipo. By the time crusaders helped Afonso Henriques take the city in 1147, it held roughly 154,000 people and had already changed hands among Visigoths, Moors, and a brief independent Muslim kingdom. Why has a city on the northern shore of the River Tagus drawn so many conquerors, traders, and refugees across three thousand years? What did a single November morning in 1755 do to the place that survivors had to invent earthquake-proof building to recover from it? And how did a port near the westernmost point of continental Europe become an alpha-minus global city of finance, fashion, and trade? Those answers begin in the harbour that started it all.

  The Tagus estuary offered a secure place to unload and provision trading ships, and that single fact shaped everything. Iron Age people occupied the Castelo hill site from the 8th to 6th centuries BC, trading with Phoenicians whose pottery still surfaces in excavations near the Castle of São Jorge. Archaeology suggests a Phoenician presence here since 1000 BC, with a trading post on the southern slope of the Castle hill, at what is now the city centre. The Tagus settlement traded with inland tribes, sending out metals, salt, salted fish, and the Lusitanian horses famed in antiquity. Under Rome, Felicitas Julia exported garum, a prized fish sauce shipped in amphorae to Rome, alongside wine, salt, and horses. A broad road linked it to Bracara Augusta and to Emerita Augusta, the capital of Lusitania. The same shelter that fed Roman elites would later launch ships toward India and Brazil.

• 3. A City Of Conquerors

  ›

  On the 6th of August 711, the Muslim forces of the Umayyad Caliphate took Lisbon, and the new rulers reshaped it. They built mosques and houses, rebuilt the city wall known as the Cerca Moura, and let Muwallads, Arabs, Berbers, Mozarabs, Saqaliba, and Jews keep their own ways. Most Christians spoke Mozarabic while Arabic was widely understood across all communities. For a short window, the Taifa of Lisbon stood as an independent Muslim kingdom from 1022 to 1034, before the larger Taifa of Badajoz absorbed it. In 1108 Norwegian crusaders led by Sigurd I raided and held the city for three years on their way to the Holy Land, before the Almoravids retook it in 1111. When Afonso I conquered the city in 1147, the chronicle Expugnatione Lyxbonensi recorded the local bishop killed by crusaders while residents prayed to the Virgin Mary. Spoken Arabic vanished from Lisbon within a generation, but its trace survives in the Alfama, whose name comes from the Arabic al-hamma.

• 4. The Golden Era

  ›

  Vasco da Gama sailed from Lisbon to India in 1498, and the wealth that followed changed the city's character. From the late 15th century into the early 17th, most expeditions of the Age of Discovery departed here, turning Lisbon into the European hub of trade with Africa, India, the Far East, and later Brazil. Riches flowed in from spices, slaves, sugar, and textiles. This wealth produced the exuberant Manueline style, visible in 16th-century monuments such as the Belém Tower and the Jerónimos Monastery, both later named UNESCO World Heritage Sites. Damião de Góis wrote a description of Lisbon in the 16th century, published in 1554. The boom had a darker side. When Spain expelled its Jews, many fled to Lisbon, yet in 1497 Manuel I decreed that all Jews must convert to Christianity. In 1506, an anti-semitic massacre by Old Christians ran for four days, killing an estimated 1,000 to 4,000 New Christians. The king, then at Évora, ordered two instigating friars excommunicated and burned alive.

• 5. The Great Earthquake

  ›

  On the 1st of November 1755, an earthquake destroyed Lisbon, killing an estimated 30,000 to 40,000 of a population between 200,000 and 275,000, and flattening 85 percent of the city's structures. The Ribeira Palace and the Hospital Real de Todos os Santos were lost. About 80 km north, at Peniche, the tsunami that followed killed many along the coast. The disaster had precedent. Before the 18th century the city had suffered eight earthquakes in the 14th century alone, five in the 16th, including the 1531 quake that destroyed 1,500 houses, and three in the 17th. The 1755 catastrophe shocked all of Europe. Voltaire wrote a long poem, Poême sur le désastre de Lisbonne, and returned to the event in his 1759 novel Candide, which many read as a critique of optimism inspired by the quake. Oliver Wendell Holmes Sr. invoked it in his 1857 poem, The Deacon's Masterpiece. Out of the rubble came a radical idea about how a city could be rebuilt to survive the next blow.

• 6. Pombal's Grid

  ›

  Sebastião José de Carvalho e Melo, the 1st Marquis of Pombal and minister to Joseph I, refused to rebuild the medieval town. He demolished what the earthquake had left and laid down a grid plan, giving the lower town its name, the Baixa Pombalina. The new centre opened around two great squares, the Praça do Rossio and the Praça do Comércio, the latter becoming the city's main access to the Tagus, later adorned by a triumphal arch from 1873 and a monument to King Joseph I. The Pombaline Baixa stands as one of the first examples of earthquake-resistant construction. Engineers tested architectural models by having troops march around them to simulate a quake. Pombaline buildings used a symmetrical wood-lattice frame called the Pombaline cage to distribute earthquake forces, and inter-terrace walls built higher than the roof timbers to slow the spread of fire. The same Enlightenment confidence would soon collide with Napoleon's armies.

• 7. Revolutions And Neutrality

  ›

  Napoleon's troops drove Queen Maria I and Prince-Regent John to flee to Brazil, and the capital of the United Kingdom of Portugal, Brazil and the Algarves sat in Rio de Janeiro from 1808 to 1821. The 20th century brought three revolutions to the city. The 5th of October 1910 revolution ended the monarchy and the 6th of June 1926 revolution established the Estado Novo. The Carnation Revolution of the 25th of April 1974 ended that regime and ushered in the Portuguese Third Republic. During World War II, Lisbon was one of the very few neutral, open Atlantic ports in Europe, a gateway for refugees and a haven for spies. More than 100,000 refugees escaped Nazi Germany through the city. The 25 de Abril Bridge, inaugurated as Ponte Salazar on the 6th of August 1966, was the longest suspension bridge in Europe before it took the revolution's date as its name. Its successor would carry a different explorer's name into a new century.

• 8. The Modern Capital

  ›

  Expo '98 marked the 500th anniversary of Vasco da Gama's voyage to India and gave Lisbon its newest district, Parque das Nações, a futuristic quarter built from an urban renewal program. Its centerpiece, the Gare do Oriente, was designed by the architect Santiago Calatrava from Valencia, with glass and steel columns inspired by Gothic architecture. The Vasco da Gama Bridge opened on the 29th of March 1998 and, at 17.2 km, became the longest bridge in Europe. Lisbon's reach now spans diplomacy and global events. Ambassadors from 86 countries reside in the city, which hosts three companies in the Global 2000: EDP Group, Galp Energia, and Jerónimo Martins. It held the European Capital of Culture title in 1994, the 2018 Eurovision Song Contest after Salvador Sobral's win with Amar pelos dois, and World Youth Day 2023, where the final mass in the Parque do Tejo drew an estimated 1.5 million attendees. Carlos Moedas became the 78th Mayor of Lisbon in October 2021 and won a second term in the 2025 local elections. Across the Tagus, the foundations for a third bridge have already been laid, waiting for the politics to catch up with the engineering.
