Portugal is often described as Europe’s best-kept secret, but for the modern traveler, it is a land of profound depth, resilient history, and massive global influence. Beyond the sun-drenched beaches of the Algarve lies a nation that has shaped the world in ways many don’t realize.
From ancient foundations to pioneering sustainability, here are 15 fascinating facts that prove Portugal is much more than just a beautiful coastline.
Portugese History & Foundations: The Roots of a Nation
1. Lisbon is Older than Rome
While Rome is the “Eternal City,” Lisbon has it beat. Settled by the Phoenicians around 1200 BC, Lisbon is the second-oldest capital in Europe (after Athens), predating Rome by nearly four centuries.
2. The World’s Oldest Borders
If you like stability, look to Portugal. Founded as a kingdom in 1139, its continental borders have remained almost entirely unchanged since 1297, making them the oldest established borders in the world.
3. The Oldest Diplomatic Alliance
The Treaty of Windsor (1386) established the Anglo-Portuguese Alliance between Portugal and England. It remains the oldest diplomatic alliance in the world still in force – a testament to Portuguese loyalty and longevity.
4. The 20-Minute King
History moves fast, but rarely this fast. In 1908, Luís Filipe technically became king for only 20 minutes following his father’s assassination. He succumbed to his own wounds shortly after, marking the shortest reign in human history.
5. The 1755 Earthquake: A Global Turning Point
The 1755 Great Lisbon Earthquake wasn’t just a natural disaster; it was a philosophical shift. The massive quake devastated the city and sparked the birth of modern seismology and new Enlightenment debates on how humanity responds to catastrophe.
Global Influence: A Reach Far Beyond the Coast
6. Pioneers of the “Age of Discovery”
Portugal essentially kicked off the Age of Discovery. Vasco da Gama found the sea route to India, and Ferdinand Magellan (Portuguese-born) planned the first circumnavigation of the globe.
7. The “Empire of Nine Nations”
Portuguese is a global powerhouse. It is the official language of nine countries across four continents. With over 260 million speakers, it is the most spoken language in the Southern Hemisphere.
8. Portugal Invented Japanese Tempura
Next time you enjoy Japanese tempura, thank a Portuguese missionary. This Japanese staple originated from peixinhos da horta (fried green beans) brought to Japan by Portuguese explorers in the 16th century.

9. The World’s Oldest Bookstore
Bibliophiles must visit Livraria Bertrand in Lisbon’s Chiado district. Open since 1732, it holds the Guinness World Record for the oldest operating bookstore and survived the 1755 earthquake.
10. The Surrealist Village of Monsanto
Voted “the most Portuguese village in Portugal,” Monsanto is built directly into giant granite boulders. The houses are squeezed between, under, and inside massive stones that look like they could roll away at any moment. It feels like a film set from another world.
11.The Knights Templar Legacy in Tomar
For fans of history and mystery, the Convent of Christ in Tomar is a UNESCO site that served as the 12th-century headquarters for the Knights Templar. Its “Manueline” style architecture, full of nautical ropes and coral carved into stone, represents the height of Portugal’s maritime power.
12. The Azores: The “Hawaii of the Atlantic”
This volcanic archipelago is a paradise of crater lakes and thermal springs. In 2026, the Azores are leading the way in eco-tourism, offering carbon-neutral hiking trails and whale-watching experiences.
Portugese Nature & Innovation
13. Cork Capital of the World
Portugal produces over 50% of the world’s cork. It is a protected industry; it is actually illegal to cut down a cork tree (Sobreiro) without government permission.
14. Surfers Paradise
At the Nazaré Canyon, the unique underwater topography creates the world’s largest waves. Surfers here regularly break world records by riding “monsters” over 24 meters (80 feet) high.
15. A Green Energy Powerhouse
Portugal is a world leader in renewable energy. As of early 2026, renewables frequently cover over 80% of the national electricity demand, utilizing a sophisticated mix of wind, solar, and hydro power.
Portuguese cuisine is a masterclass in tradition and flavor, yet it remains one of Europe’s most “criminally underrated” culinary landscapes. No journey through the country is complete without tasting the dishes that define its soul—and pairing them with the world-class wines that have been produced here for centuries.
If you only try three things, make it these:
Bacalhau: Salt cod is the undisputed king of the Portuguese table, famously prepared in over 365 different ways—one for every day of the year.
The Pairing: Try it with a medium-bodied white from the Dão region (look for the Encruzado grape) or even a light red from the Douro Valley for heartier preparations like Bacalhau à Brás.
Pastel de Nata: These iconic, flaky custard tarts are a national obsession. They are best enjoyed warm from the oven with a light dusting of cinnamon and powdered sugar.
The Pairing: Elevate the experience with a chilled glass of Moscatel de Setúbal or a Tawny Port. The honeyed, nutty notes of these fortified wines are a match made in heaven for the creamy custard.
Grilled Sardines: Simple and rustic, these are the quintessential taste of a Portuguese summer, best enjoyed fresh at a local street festival.
The Pairing: You need the crisp acidity of a Vinho Verde (Green Wine). Specifically, look for an Alvarinho from the Minho region; its citrusy zest cuts through the richness of the oily fish perfectly.
