In the early days F1 had some interesting circuits, one of them is Bremgarten circuit of Switzerland.
Some circuits disappeared because they became outdated, and some vanished simply because the sport moved on.
It was hidden deep inside the Bremgartenwald forest near Bern in Switzerland.
The circuit was beautiful and very fast, surrounded by trees and nature, but drivers feared it.
Today, parts of it still exist, but its story belongs to another era.
Bremgarten Circuit: Built Inside a Forest
In the early days, circuits were not designed with safety in mind, and this circuit was never built as a permanent racing track.
However, the track was long, around 7.28 KM, and what made it unique was not its length, but it was its character.
Almost no true straights, the circuit was made up of fast, flowing corners that never seemed to end. Drivers had to fight the car constantly, the forest created a tunnel effect, with trees lining both sides of the road, leaving no room for mistakes.
Shadows, made it harder for the drivers, sunglight struggled to break through the trees, just like Isle of TT today, leaving sections of the track dim and unpredictable.
There were no runoffs, no barriers, and once you made a mistake at Bremgarten, there was nowhere to go.
In the early days of F1, there were many long circuits, such as the Nürburgring and the original Spa-Francorchamps. However, the longest of them all was the Pescara circuit, a legendary track that no longer exists.
When Champions Ruled the Forest
Bremgarten circuit became part of F1 history when it hosted the Swiss GP during the early years, from 1950 to 1954.
The drivers who won there were not ordinary drivers, but legends, Guiseppe Farina was the first winner in 1950, that year he became a World Champion.
A year later, Juan Manuel Fangio conquered the forest; 1951, then the next two races, both dominated by Ferrari drivers, Piero Taruffi in 1952, and Alberto Ascari in 1953.
Again in 1954, it was Fangio, this time driving for Mercedes, and his victory would become the final F1 race ever held at Bremgarten circuit.
No one knew it at the time, but an era was ending.
A Beautiful Circuit With a Dark Reputation
Drivers respected Bremgarten, but they also feared it, hidden behind the beauty of the forest, but the visibility was poor, especially in changing light conditions.
Also the surface was unpredictable, fast corners, no modern safety systems, and no advanced protection.
Yet drivers still raced there, pushing their cars to the limit.
Back in the early days, F1 did not race only on forest circuits like Bremgarten. There were many others, some now almost completely forgotten, such as the Circuit of Lisbon in Portugal. Now completely demolished and forgotten.
The Disaster That Changed Everything
The end of Bremgarten come not because of something that happened there, but it was the Le Mans in 1955 accident.
Switzerland reacted immediately, the country banned circuit racing entirely, overnight, Bremgarten’s future disappeared!
There was no final farewell. No final race to say goodbye. The circuit was simply abandoned.
The forest grew quiet again.
What Remains Today

Unlike many lost circuits, Bremgarten was never completely destroyed, because it was built on public roads, much of the layout still exists today.
Drivers who once fought for victory there have been replaced by ordinary cars, bicycles, and some section have been absorbed into modern infrastructure.
The A1 autobahn cuts through part of the original layout, other areas have been covered by houses or reclaimed by nature.
No pit buildings or grandstands, everything is gone, nothing remains of the racing facilities.
But if you look closely, you can still follow curves, you can still drive in some parts of the same roads where Fangio once raced.
Why Bremgarten Could Never Return
In recent years, Switzerland has begun relaxing its motorsport restriction, with the legal ban on circuit racing finally being lifted, but Bremgarten will never return to F1.
Modern F1 tracks require massive runoff areas, and Bremgarten circuits with its narrow forest roads and blind corners, could never meet those requirements without being completely rebuilt.
And if it were rebuilt, it would no longer be Bremgarten, it would lost the very character that made it legendary.
A Circuit Frozen in Time
Bremgarten circuits represents a lost era of F1, an era when circuits were carved into forests.
Today, there are no engine screaming through the trees, only silence remains, but for those who know its story, Bremgarten is not just a forgotten circuit, it is a reminder of how far F1 has come.
