The 1755 Earthquake Of Lisbon
The 1755 earthquake in Lisbon remains one of the most devastating natural disasters in European history. But what makes this event stand out, and why is it still remembered today? In this post, we’ll explore the key reasons why the 1755 earthquake of Lisbon was such a significant event.
Why The 1755 Earthquake Of Lisbon Was Such A Big Deal
1. The Earthquake: A Massive Shaking
The earthquake that struck Lisbon on November 1, 1755, was the largest ever recorded in Europe. It’s estimated to have reached a magnitude of 8.5–9.1 on the Richter scale, though it happened long before modern seismology could provide an exact measurement. The force was so powerful that it caused near-total destruction throughout the city.
2. Tsunamis: Waves of Destruction
Following the earthquake, a series of devastating tsunamis slammed Lisbon’s coastline. The tidal waves surged up the river and flooded much of the city, including the heart of the historic center. The most significant wave even reached the Rossio area, causing additional death and destruction.
3. Fires: A City Engulfed in Flames
In addition to the earthquake and tsunamis, fires broke out throughout Lisbon, fueled by candles that had been lit all around town to celebrate All Saints’ Day. These fires burned uncontrollably for nearly a week, compounding the devastation. Without modern firefighting equipment, the city had no way to stop the flames that consumed what remained after the shaking and flooding.
4.The Timing: All Saints’ Day
The earthquake struck on one of the most important days in the Catholic calendar—All Saints’ Day, on November 1, 1755. At around 9:40 AM, most of Lisbon’s population was attending church services. The majority of those who perished in the quake were inside churches when the ground started shaking.
5. The Scale of the Destruction
About 85% of Lisbon’s buildings were destroyed, including the majority of the city’s infrastructure. The earthquake left the city in ruins, disrupting daily life and leaving thousands of people homeless.
6. The Death Toll: Lives Lost
It’s estimated that up to 40,000 people died in the disaster, which accounted for around 20% of Lisbon’s population at the time. This staggering loss of life shocked not only Portugal but also the wider European world.
7. Birth of Modern Seismology
The 1755 Lisbon earthquake was the first major earthquake to be studied systematically, sparking the development of modern seismology. It was a pivotal moment for scientific study, laying the groundwork for better understanding of earthquakes and their impacts on societies.
8. Rebuilding Lisbon: A New Beginning
After the destruction, Lisbon’s reconstruction began under the leadership of the Marquis of Pombal. The downtown area (Baixa) was completely redesigned, transforming from a medieval maze of narrow streets into a modern, grid-like layout. The city’s new design made it more resilient to future earthquakes.
9. Pombaline Architecture: Earthquake-Resistant Buildings
One of the lasting legacies of the 1755 earthquake is the Pombaline style of architecture. The buildings in the Baixa district were the world’s first earthquake-resistant structures, known as “gaiola Pombalina” or the “Pombaline cage.” These buildings featured a wooden framework designed to shake without collapsing, offering a blueprint for earthquake-resistant construction.
10. A Curious Story: The Brothels of Bairro Alto
Interestingly, one area of Lisbon that survived relatively untouched was Bairro Alto, the city’s historic district of brothels. While religious buildings were destroyed, the brothels in Bairro Alto remained standing, much to the embarrassment of the Catholic Church. This contrast added to the shock and drama surrounding the disaster.
11. King Joseph I: A Changed Monarch
King Joseph I, who ruled at the time, narrowly survived the earthquake. He was away from the city, celebrating All Saints’ Day in his palace in Belém. However, the trauma of the event left him emotionally scarred. From that point on, the king lived in fear of another earthquake, even setting up a temporary residence in the hills outside Lisbon in case of future disasters.
12. The Marquis of Pombal: The Hero Who Rebuilt Lisbon
The Marquis of Pombal, Portugal’s prime minister, was the central figure in Lisbon’s recovery. His decisive leadership helped stabilize the country in the wake of the disaster. He oversaw the reconstruction of the city, consolidating power and eliminating opposition. His vision for a modern, earthquake-resistant Lisbon remains a significant part of the city’s legacy.
Conclusion: The Legacy of the 1755 Earthquake
The 1755 earthquake of Lisbon remains one of the most important events in European history. It not only changed the face of Lisbon but also had a profound impact on the fields of science, architecture, and philosophy. Today, the memory of the earthquake serves as a reminder of the power of nature and the need for preparedness in the face of disaster.
