The Calgary tower is an iconic building in the down town core of Calgary. It is now a dwarf compared to other buildings like the Bow, however it has it's own charm and amazing views nevertheless!
The glass floor is an awesome treat once you arrive to the top! Hopefully you go on a nice clear day as to get the most of all the views! Also be sure to bring a camera! They have a gift shop if you like that sort of thing and apparently a really fancy restaurant inside if you want to make reservations and spend a lot of money.
I recommend checking it out at least once!
