Watch this breathtaking moment as a British Daredevil scales the world’s tallest freestanding climbing wall without any ropes or safety equipment.

It took the 18 year old just 15 minutes to free solo up the high wall.

Named after the sword of the mythical King Arthur, the Excalibur climbing wall located in Groningen, Netherlands stands over 121 feet (37 meters) in the air.

Free soloing is extremely dangerous, and can result in serious injury or even death.
