One of the most famous houses in Odessa is located at Vorontsovsky Lane, 4 (you can get to the lane from Primorsky Boulevard). If you stand in a certain place of the alley opposite this house, then it seems that the house is completely flat, as if consisting of one facade wall. Imagine, you see that the house is residential, there are curtains hanging on the windows, clothes are drying on the balconies, there are flowers in tubs...And the house is flat! Such an illusion is created by one of the walls of the house, which is at an acute angle with respect to the street.→
