In Monaco, there is an incredibly secretive car collection underground that is guarded, with no photos or videos allowed to be taken.
Monaco is famous as the home of a Formula 1 Grand Prix and as the playground for the rich and famous.
It therefore makes sense that plenty of cars, ranging from supercars, luxury cars, and classic cars, should find their home in the principality.
This secret collection, however, has a huge amount of mystery surrounding it. Nobody is sure what is down there, and nobody is allowed to take any photos of the cars.

Where is the secretive car collection in Monaco located?
A post on Reddit hinted at where the secret collection is located.
The post says that it is at a casino parking lot and sits below the last level, level H.
Below that, it is said there are two floors that are private, and one is reached by a very steep grey ramp.
One of the two garages down there is filled with old cars and motorbikes in perfect condition.

However, there is also a gate that hides what appears to be a more modern garage.
At the bottom, an image shows the garage, with a Ferrari at the front and a light pointed at it.
Beyond that, no one is sure what is in the garage.
Security will escort you away from the garage
The Reddit user who posted the image of the garage said there is no chance you can get a look at the cars.
If you were there for around a minute, a guard would block your view and then escort you out of the area.
They also apparently check to make sure you haven’t uploaded anything to social media or taken a picture.
The poster said that they also have a video of the garage entrance, along with the photo that they uploaded.
This could be the only photo of this particular garage to exist.
It adds another layer of mystery as to what might be hiding in this secret garage.
Maybe it’s full of long-lost cars that its owner doesn’t want us to know about!
