In fact, we only discovered it 5 years ago — and it's still being built as we speak.
That's all because this is a prime example of something we call Revivalism... 🧵
We often think of medieval castles as relics of a forgotten era — symbols of feudal power or romantic ruins.
Yet, in the modern world, visionaries are building wonders inspired by this very period.
This is Stobnica Castle.
It lays hidden on an artificial island in the forest of Western Poland.
At first glance, Stobnica appears to belong to the medieval world, with its towering spires, turrets and stone walls.
But construction began in 2015 — it was only “discovered” via drone, in 2020
We don't actually know who or why it was built...
But we do know that it has a 90-meter high tower and is 15-storeys high — each floor is twice the height of a typical residential one.
However, Stobnica is not alone and it's not the first *modern* medieval wonder.
It's a prime example of Revivalism.
Where you use elements of a previous architectural era to build old buildings, but in modern times.
Here's New York State Capitol, in Albany — built in Romanesque Revival.
It might not have crossed your mind before, but Big Ben is actually one of the most famous examples of Revivalism.
More specifically, it was built in Gothic Revival after Parliament had burned down, in 1834.
You might have also heard of Guédelon Castle, in France.
Every worker operates as though the modern world doesn’t exist.
Using only tools and materials that would have been available in the 13th century.
And that's what makes it unlike anything you have ever heard of.
Work began in 1997, and tries to imitate the Middle Ages as closely as possible.
The architecture is very specific too: built in the transitional Romanesque and early Gothic phase, under Philip II of France.
A typical medieval stronghold like this even includes a simple wooden bridge — but not a drawbridge.
This is an important feature: it’s a nobleman’s castle, not a royal one, so its owner would not be able to afford a drawbridge or moat.
But it's not just about literally reliving history.
Techniques that were redeveloped by builders in Guédelon are incredibly important.
They were used to help perfectly reconstruct the roof of Notre-Dame de Paris, which opened last year.
Something else quite remarkable about it all is that it has a medieval crane that can lift half a ton of materials — powered completely by a treadmill.
So now we’ve seen two castles, but there is also an attempt to rebuilt a monastic community right from the Middle Ages in Germany: Campus Galli.
This project aims to replicate what we see in the Plan of Saint Gall — the only surviving architectural drawing from the Middle Ages.
Building wonders from the past, in the present, isn’t an idea that is relatively new.
Revivalism has been around for centuries.
Take one of the most famous examples you could think of: Neuschwanstein Castle.
King Ludwig was inspired by medieval and Byzantine architecture and built his own "fairytale" castle.
It had everything you could have asked for in the 19th century.
From central heating and flushing toilets to an artificial cave.
And there's also Palais Garnier — one of the most stunning places in Paris.
Beuax-Arts references everywhere.
But it's interior is Neo-Baroque.
Or the Panthéon, (not in Rome but) also in Paris.
Built in the Neoclassical style, as an 18th-century mausoleum, housing tombs of Victor Hugo, Voltaire and Marie Curie.
Here's Schwerin Palace, in Germany (1857)
A pompous example of Renaissance Revival.

If you like the Parthenon, then you'll love ancient Greek architecture.
2,500 years ago, it produced some of the greatest wonders the world has ever seen.
Here are the best ones.. 🧵
1. Temple of Concordia, Sicily, Italy (430 BC)
2. Theater of Epidaurus, Argolis, Greece (4th century BC)
Designed by architect Polykleitos the Younger, this 14,000-seat theater is renowned for its nearly flawless acoustics; even a whisper on stage reaches the highest tier.
3. Temple of Hephaestus, Athens, Greece (415 BC)
It is said to be the best-preserved Doric temple of Greece and is located on the western edge of the Ancient Agora, a large open square that was the center of ancient Athenian life.
This is not a microchip — it's the Forbidden City, in China.
What makes it so special?
600 years ago, it had exactly 9,999 rooms, not a single structure you see here was built with a nail and 40% of the Forbidden City is still "forbidden"... 🧵
The true scale is unprecedented.
That's because it's larger than the White House, Buckingham Palace and Vatican City combined but took just 14 years to build.
So it's amazing but what actually is it?
It's the largest palace complex in the world.
It has 90 palaces that have been home to 24 different Chinese emperors, over its lifespan.
And it was even briefly under the control of Anglo-French forces, in 1860, during the Arrow War.
