Towers are perfect for my Halloween and Day of the Dead display. The space is perfect 13.5 high by 11.5 square base. In all the tower stands 57.1\4" high. They compliment the fireplace. 
The 2 other towers: 
The 3rd Tower is in a spare bedroom for knickknacks and a lamp.
The 4th Tower is in my office to store my mobile devices (Laptop, Tablet, Notebook, mobile phone, and accessories) and a desk lamp, next to my desk. Perfect solution in my case.
