Exploring the darker side of Lisbon’s soulful past
As much as I love sharing Lisbon’s sunshine, viewpoints, and pastel de nata stops, I’ve always believed that truly understanding a city means looking at its harder chapters too. Over time, living here and digging deeper into Portugal’s history — through museums, local archives, and conversations with residents — I’ve come to realize that Lisbon’s past isn’t only made up of discoveries and golden ages. There are darker moments that shaped the city just as profoundly.
In this guide, I’m exploring ten of the more difficult chapters in Lisbon’s history — from political turmoil to natural disasters and periods of repression. My aim isn’t to sensationalize the past, but to understand it more fully, and to recognize how these events helped shape the Lisbon we experience today.
A City of Light… and Shadow
Lisbon is celebrated for its sunny terracotta rooftops, colorful azulejos, and romantic viewpoints overlooking the Tagus River. Travelers love its slow rhythm, pastel hues, and fado echoing through Alfama’s narrow alleys.
But beneath that beauty lies a history shaped by religious persecution, imperial exploitation, deadly disasters, political oppression, and human suffering. The darker chapters of Lisbon’s history give the city depth and emotional gravity—making every miradouro, convent wall, and cobbled square feel more meaningful.
This guide goes beyond the surface to explore Lisbon’s shadowed past, the places where history unfolded, and how you can visit them today through museums, guided tours, and immersive experiences.
10 Dark Chapters in Lisbon’s History: Unveiling the Shadows of the Past
1. The Portuguese Inquisition (1536–1821) ⚖️
One of the darkest eras in Portuguese history, the Portuguese Inquisition aimed to enforce religious conformity and Catholic authority.
Jews, Muslims, Protestants, and “heretics” were hunted
Thousands had their wealth seized
Many were imprisoned, tortured, or burned alive in public
Rossio Square, today a lively and central meeting point, was once a stage of terror—where executions were held before crowds. It is impossible to stand there without imagining the dread and spectacle that once filled the space.
2. Lisbon and the Transatlantic Slave Trade ⚓
From the 1400s onward, Lisbon was one of the biggest slave-trading ports in Europe. Tens of thousands of enslaved Africans were:
Arriving directly in Lisbon’s harbor
Sold in markets and squares
Forced into labor across farms, households, and colonies
This horrific industry built fortunes, funded palaces, and fueled Portuguese imperial expansion. Today, Lisbon is finally starting to acknowledge these roots through museum exhibits, public memorials, and academic research.
To learn more firsthand:
Visit the Alfama Slave Market Memorial, a sobering tribute to stolen lives
Explore historic stone quays where slave ships once docked
Take a dedicated African diaspora or slave trade history tour
☝️ A powerful recommendation:
👉 Some of the most poignant guided tours in Lisbon trace the origins, sites, and legacy of the slave trade—often hosted by expert historians. These can be booked through GetYourGuide and are among the most eye-opening experiences in the city.
3. The Lisbon Massacre of 1506 🔥
In 1506, religious hysteria and intolerance erupted into one of Portugal’s worst massacres. Over three days:
Mobs murdered more than 2,000 New Christians
People were beaten, burned alive, and executed
Certain clerics celebrated and encouraged the violence
A somber memorial now stands outside São Domingos Church, marking the site of the bloodshed.
4. The 1755 Earthquake – A Day That Changed Europe 🌊
On All Saints’ Day 1755, Lisbon faced what may have been Europe’s most devastating natural disaster:
A massive earthquake (estimated 8.5–9.0)
A tidal wave that crashed into the waterfront
Firestorms that consumed the ruins for nearly a week
Up to 60,000 people perished, and nearly the entire city center collapsed. The event shocked Europe, influenced Enlightenment philosophy (Voltaire wrote angrily about it), and transformed Lisbon into a test lab for early earthquake-resistant urban planning.
Today, the haunting open-air Carmo Convent remains one of the most dramatic reminders of that day.
5. The Estado Novo Dictatorship (1933–1974) 👤
Under António Salazar, Portugal lived under censorship, authoritarianism, and fear:
The PIDE secret police arrested and tortured citizens
Free speech disappeared
Dissidents were jailed or forced into exile
Media and education were heavily controlled
The dictatorship ended peacefully during the Carnation Revolution in 1974, when soldiers carrying flowers instead of rifles reclaimed democracy.
To explore this era, the Museu do Aljube – Resistance and Liberty is one of the best museums in Lisbon—and many tours include it as a highlight.
6. Public Executions as Spectacle ⚔️
For centuries, public punishment was not only legal—it was theatrical. Lisbon’s main squares played host to:
Hangings
Beheadings
Burnings
Public torture
Crowds gathered like an audience at a play. Today, it is striking to walk through places like Rossio Square knowing how vastly different the atmosphere once was.
7. Cholera Epidemics of the 19th Century ☣️
In the 1800s, waves of disease ravaged Lisbon. Cholera and typhoid outbreaks were fueled by:
Contaminated drinking water
Overcrowded working-class neighborhoods
Minimal sanitation infrastructure
Thousands died. The tragedy finally pushed the city toward modern public health reforms, shaping the clean, tiled Lisbon we see today.
8. The Expulsion of the Jesuits (1759) ⛪
Following the earthquake, the powerful reformer Marquis of Pombal accused the Jesuits of holding back national progress. He ordered:
Total expulsion from Portugal
Closure of Jesuit schools
Seizure of lands and assets
This upheaval reshaped Portugal’s educational landscape and redefined the role of church and state.
9. The Liberal Wars (1828–1834) 🏰
Lisbon became a battlefield during a civil war between:
Absolutists supporting King Miguel
Constitutionalists demanding liberal reforms
The fighting led to:
Urban combat
Economic collapse
Social trauma
In the end, Lisbon chose the path of constitutional monarchy, paving the way for modernization and political evolution.
10. The Chiado Fire (1988) 🔥
One of Portugal’s greatest modern tragedies, the Chiado Fire:
Destroyed 18 historic buildings
Displaced hundreds
Devastated a beloved district
Restoration required more than a decade and renewed commitment to historic preservation. Today Chiado thrives again—but the fire changed the city forever.
