A famous California climber became the first person to ever climb the Royal Ontario Museum (ROM).

Kevin Jorgeson, who usually climbs California mountains, climbed the ROM’s Crystal peaks on October 26 as bystanders gathered to watch the “urban mountaineer.”

“It has always been a big dream of mine to climb a big, beautiful building,” said Jorgeson in front of The ROM’s Crystal.

The first stunt of its kind at the ROM, Jorgeson proved that no peak is out of reach. Check out photos from his climb below!
