The CN Tower in Toronto, Canada was built in 1976 to solve a big TV problem — tall buildings were blocking TV signals, so they needed something super tall to broadcast from!
The CN Tower’s name comes from its original owner, Canadian National Railway, who wanted to show how amazing Canadian engineering could be!
The CN Tower took 1,537 days (about 40 months) to build, with construction workers braving heights and weather to complete this amazing structure!
The CN Tower’s foundation is as deep as 10 swimming pools stacked on top of each other — it goes 15 meters (49 feet) into the ground!
During construction of the CN Tower, a huge Sikorsky helicopter nicknamed “Olga” helped lift the massive antenna to the top!
