This striking optical illusion makes a well known industrial building in Ontario look at lot larger than it actually is.
Situated in Port Colborne, Ontario and dating back 100 years, the mill only started to gain attention relatively recently when people started noticing something distinctly odd about its size.
If you happen to be approaching the mill from one particular direction, from a distance it looks as though the mill is absolutely gigantic with its hulking shape dominating the horizon.
As you drive closer, however, the mill seems to get smaller and smaller, taking up less and less of the horizon until, upon reaching the water, it appears relatively small and far off in the distance.
This optical illusion is so striking that some visitors have taken to turning around and experiencing it a second time, just to make sure that they weren't imagining things.
In reality, the reason that the mill appears so large from further away is down to a trick of perspective with the trees and the angle of the road adding to the effect.
