Tallest building in each state #19, Republic Plaza, Denver, Colorado
Welcome to the Mile High City, home to the tallest buidling in Colorado, Republic Plaza. This one's a pretty tall one coming in at 714 ft and 56 stories. The tower is used as office space. As a kid, I learned what the tallest buidling in each state was. I plan on visiting each one, and also placing a geocache at each one. Cache is a magnetic nano. Good luck!
