It’s time to relax and give your brain a good workout with the help of a viral puzzle that’s been generating quite a stir online. In today’s mental workout, you’ll be asked to spot the errors that have been skillfully camouflaged in two vintage-style photographs of the countryside.

The first image depicts a famous windmill surrounded by verdant meadows and a clear river. Something in the image, though, isn’t quite right. Discover what it is! If you can notice the error in less than 20 seconds, you are a true genius.

Though it may take you a little longer to notice the fault in the image, don’t close up because everyone who spots the error is a winner. Take your time and look at the image again. To assist you with this difficult work, we can reveal that the error is related to the windmill.

Given the conditions depicted in the image, the structure will be unable to function! If you’re still seeking for the error, check closer at what’s around the windmill. Do you see the elevated platform surrounded by a fence? What about those steps? As it occurs, the staircase is visibly blocking the windmill blades, preventing them from rotating!
