A secret bedroom strangely located in Berlin subway system caught the attention of German media this week. The concealed room which is tastefully designed consists of a yucca, a single bed, a small armchair and a dime stone art hanging on the wall. It was discovered after a routine fire inspection in the tunnels.

The secret bedroom dubbed secret apartment has a mysterious bedchamber of unknown origin, City Lab reports. There is a bizarre graffiti on the grubby metal handrail. Staff of the city's U9 subway line has no idea of its existence until they found it in December 2015.  With the appearance of the photos, the place looks scary and magical at the same time.

A report published by Berliner Zeitung claims that the room has a 1980s look. There is a TV room and mounted wallpaper and carpet. The bed has a varnished frame and a mattress covered with blue and flower bedding. The secret room has a wallpaper with Matisse, and there's also a photo of a woman hanging in the room. A plant usually found in the warm regions of Mexico and North America called Yucca is seen displayed in the corner. A small, old television is placed on a small table. An eye-catching rice paper ball lamp is also hanging from the ceiling.

"That's dangerous cross," says BVG spokeswoman Petra Reetz. "There was power everywhere turned. One false step, a fast-moving train zoom could mean death."

As the secret bedoom under the Berlin tunnel was heavily featured by the media, no one knows who really took the photos which are now being distributed in the tabloids. Meanwhile, authorities at BVG believe that anyone who built the secret room must face a consequence. They claim that it is a case of trespassing. After it was discovered, the secret room including its furniture under the subway was removed.
