The Secrets of Freiburg

Where Gothic Spires Meet Black Forest Streams

Founded in 1120 by the Dukes of Zähringen as a free market town, Freiburg im Breisgau has spent nine centuries at the crossroads of German, French, and Swiss culture. Its Münster cathedral survived WWII almost untouched while the city around it burned. Tiny medieval Bächle waterways still thread through cobblestone streets, and the Black Forest rises just beyond the old town gates. This hunt takes you through 10 landmarks spanning 900 years of history.

The Age of Faith
A Spire That Survived the Inferno

For over 300 years, stonemasons built toward heaven. Then, in 1944, bombs flattened the city — but the cathedral stood.

Freiburg Münster
Gothic · 1200–1513
You stand before what Jacob Burckhardt called “the most beautiful spire on earth.” Construction began around 1200 in Romanesque style under the last Duke of Zähringen, then shifted to Gothic as generations of masons raised the 116-metre tower. On November 27, 1944, Allied bombers destroyed nearly all of Freiburg’s old town in twenty minutes. The Münster, miraculously, survived almost unscathed — its spire still piercing the smoke-filled sky. Today, 19 bells totalling 25 tonnes ring out over the market square below.
🧩 Riddle
The Münster’s famous openwork spire rises to what height?
💡 Need a hint?
Think of a football pitch — it’s a bit longer than that, standing upright...
🎉 The Answer
B. 116 metres
The spire is exactly 116 metres tall. Swiss historian Jacob Burckhardt called it “the most beautiful spire on earth.” The cathedral holds 19 bells weighing 25 tonnes combined — one of Germany’s largest peals.
Medieval Engineering
The City Built on Running Water

While other towns relied on wells, Freiburg engineered an underground network of streams threading through every street.

💧
The Bächle
Medieval · 13th Century
Look down. Those narrow channels of crystal-clear water running alongside the cobblestones? They’re the Bächle — over 15 kilometres of tiny waterways fed by the River Dreisam. First documented around 1220, they once served as the city’s fire brigade, waste disposal, and livestock water supply. The entire old town was raised by up to three metres to maintain the gradient. Legend says: if you accidentally step in a Bächle, you’ll marry a Freiburger.
🧩 Riddle
What was the original primary purpose of the Bächle in the Middle Ages?
💡 Need a hint?
Think about a city’s worst nightmare before fire engines existed...
🎉 The Answer
B. Water supply and firefighting
The Bächle span over 15 km throughout the old town. The entire city centre was raised up to 3 metres to create the gradient needed for flow. The first written record dates to around 1220.
Habsburg Freiburg
The Crimson Palace of Commerce

When the Habsburgs needed a building to show who ruled the Breisgau, they painted it blood-red and covered it in coats of arms.

🏛️
Historisches Kaufhaus
Late Gothic · 1520–1532
The Historisches Kaufhaus is impossible to miss — its deep crimson facade dominates the south side of Münsterplatz. Built between 1520 and 1532 by Cathedral Master Builder Lienhart Müller, it served as the Habsburg customs and trading house. Four ornate bay windows display the coats of arms of four Habsburg rulers. After WWII, from 1946 to 1952, it became the state parliament of Baden — democracy rising from the ashes.
🧩 Riddle
This striking building served an unexpected political role after WWII. What was it?
💡 Need a hint?
Think about government, not commerce...
🎉 The Answer
B. State parliament of Baden
From 1946 to 1952, the Historisches Kaufhaus served as the state parliament of Baden. The building’s four bay windows display coats of arms of Habsburg rulers including Emperor Maximilian I.
The Walled City
Through the Gate of Saint Martin

Of five original city gates, only two survive. This one once imprisoned those who crossed the law.

🏰
Martinstor
Medieval · 1202
Dendrochronology dates the Martinstor’s wooden beams to 1202, making it one of Freiburg’s oldest standing structures. For centuries, it served not only as a city gate but also as a prison — inmates were said to have “donned the Cloak of Martin.” In 1901, architect Carl Schäfer dramatically heightened the tower from 22 to 60 metres, adding a new roof in 15th-century Gothic style. Today it stands as a gateway between the shopping district and the medieval old town.
🧩 Riddle
In 1901, the Martinstor was dramatically altered. What changed?
💡 Need a hint?
The tower got much, much taller...
🎉 The Answer
B. Its height tripled from 22 to 60 metres
The tower was raised from 22 to 60 metres in 1901 by architect Carl Schäfer. First documented in 1238 as “Porta Sancti Martini,” its wooden beams date to 1202.
Gates and Legends
The Swabian’s Folly

The second surviving gate hides a legend about a merchant, two barrels, and a very disappointed wife.

⚙️
Schwabentor
Medieval · 13th Century
Built in the mid-13th century, the Schwabentor is Freiburg’s eastern gateway. Its exterior wall bears the image of St. George slaying the dragon — Freiburg’s patron saint. Legend tells of a Swabian merchant who tried to buy the entire city with two barrels of gold. When opened, they contained only sand — his wife had swapped the gold to prevent his foolish purchase. Since 1969, a museum inside displays over 9,000 tin figures recreating scenes from the region’s history.
🧩 Riddle
How many tin figures are displayed in the museum inside the Schwabentor?
💡 Need a hint?
Think thousands, not hundreds...
🎉 The Answer
C. About 9,000
The Zinnfigurenklause inside the Schwabentor houses about 9,000 tin figures arranged in dioramas depicting regional history. The gate’s keystone shows a Romanesque “Boy with Thorn” — an ancient motif reinterpreted in Christian theology.
Civic Power
Two Halls, One Deception

The “New” Town Hall is actually older than the “Old” one. Freiburg enjoys its paradoxes.

🏢
Altes & Neues Rathaus
Renaissance · 1559 / 1901
The Neues Rathaus (New Town Hall) was a university building for over 300 years before the city purchased it in 1891 for 140 gold marks and converted it by 1901. The Altes Rathaus (Old Town Hall), built in 1557–59 by combining several medieval houses, actually came later. A 1944 bombing left only its outer walls. Between the two buildings, a carillon chimes daily at 12:05 pm. The Tourist Information office now occupies the Old Town Hall’s ground floor.
🧩 Riddle
Which town hall is paradoxically the older building?
💡 Need a hint?
Names can be deceiving in Freiburg...
🎉 The Answer
B. Neues Rathaus (New)
Despite its name, the Neues Rathaus is the older structure — it existed as a university building centuries before becoming a town hall. The city paid just 140 gold marks for it in 1891.
Art Among the Ruins
Where Monks Became Masterpieces

A 13th-century Augustinian monastery, now home to the most important art collection in the Upper Rhine region.

🏨
Augustinermuseum
Gothic Monastery · 13th Century
The Augustinian friars settled here in the 13th century. After secularization, their monastery became a storage depot, then a barracks, and finally — an art museum. Inside, you’ll find original stone sculptures and stained glass from the Münster, medieval altarpieces, and works spanning to the 19th century. The highlight: gargoyles and architectural fragments rescued from the cathedral, displayed at eye level so you can see details invisible from the street.
🧩 Riddle
What was this building before it became a museum?
💡 Need a hint?
Think religious community, not military or commercial...
🎉 The Answer
B. An Augustinian monastery
The museum houses original Münster sculptures and stained glass brought inside to protect them from weathering. You can see gargoyles at eye level that were once 50 metres above the ground.
The Age of Enlightenment
The Fifth-Oldest in Germany

When the Habsburgs founded a university in 1457, they planted a seed that would make Freiburg a city of thinkers.

🎓
Old University
Founded 1457
The Albert-Ludwigs-Universität was founded in 1457 by Archduke Albrecht VI of Austria, making it the fifth-oldest university in Germany. The Alte Universität building replaced the original in 1773 when the Jesuit order was dissolved and their premises transferred to the university. Today over 25,000 students keep the city youthful. The nearby Bertoldsbrunnen fountain commemorates Berthold III of Zähringen, who founded the city, and Archduke Albrecht, who gave it a university.
🧩 Riddle
In what year was the University of Freiburg founded?
💡 Need a hint?
Think mid-15th century — Gutenberg had just printed his Bible...
🎉 The Answer
C. 1457
Founded in 1457, it is Germany’s fifth-oldest university. Alumni include philosophers Martin Heidegger and Edmund Husserl, plus multiple Nobel laureates.
The Fortress Above
A Hill of a Thousand Battles

For a millennium, whoever held this hill controlled the gateway to the Black Forest.

🏔️
Schlossberg & Schlossbergturm
Fortified since 11th Century
Rising 456 metres above sea level just east of the old town, the Schlossberg has been fortified since the 11th century. Every ruler — Zähringen, Habsburg, French — built and destroyed fortifications here. In 1745, the French demolished the fortress. Today the Schlossbergturm, a 33-metre observation tower built in 2002 and designed by local architect Hubert Horbach, offers a 360-degree panorama: the Münster’s spire, the Rhine plain, the Vosges mountains in France, and the Black Forest peaks behind you.
🧩 Riddle
How tall is the modern Schlossbergturm observation tower?
💡 Need a hint?
It’s roughly a third of the Münster’s height...
🎉 The Answer
B. 33 metres
The Schlossbergturm stands 33.27 metres tall, built in 2002. The Schlossbergbahn funicular, opened in 2008, replaced Germany’s only inner-city aerial cableway that operated from 1968 to 2006.
The Green Future
The Neighbourhood That Powers Itself

On a former French military base, Freiburg built one of the world’s most radical experiments in sustainable living.

☀️
Vauban — Solar Settlement
Ecological · 1990s–2006
The Vauban district was once a French military barracks. After reunification, the land was released and Freiburg made a bold decision: no fossil fuels, no car-centric planning. Architect Rolf Disch designed the Solarsiedlung (Solar Settlement), where every house produces more energy than it consumes — the first “plus-energy” neighbourhood in the world. Streets are car-free. 5,000 residents live here. The district became a global model for sustainable urban planning.
🧩 Riddle
What is special about the houses in the Solarsiedlung?
💡 Need a hint?
They don’t just save energy — they do something extra...
🎉 The Answer
B. They produce more energy than they consume
Designed by Rolf Disch, the Solarsiedlung was the world’s first plus-energy neighbourhood. Each house generates more electricity than it uses via rooftop solar panels. Vauban is now a pilgrimage site for urban planners worldwide.
