A German tourist illegally scaled the Great Pyramid of Giza and was promptly arrested by Egyptian police when he climbed back down.
He was halfway up the ancient tomb, built around 2560 B.C., when people started shouting at him and the cops showed up, he wrote. But he didn't care and kept climbing while listening to music, he said.
"From the very top of the Cheops Pyramid. It took me around 8 minutes to reach the top. Climbing down took me 20 minutes. Safety first!" he wrote next to an image with his feet showing in the bottom of the frame.
The pyramid is the oldest of the Seven Wonders of the World and the only one to remain intact.
“It was absolutely surreal standing on top of one of the wonders of the world and something that I will never forget. I wanted to experience Egyptian culture and I definitely managed that," he told Britain's The Telegraph.
"When I got back down, the police were quick to take me to the station and question me. They also had a look at my camera to see what I had been up to."
He was released without incident, he said.
