What do people do when they do not have enough money to build a proper house with four walls? They build a house with three walls! And they leave the wondering, amazement and surprised photo shoots for those off-the-beaten track travelers, who dare to explore the real neighborhoods of Odessa. The House, located on Vorontsov Lane, is minutes away from the Mother-in-Law bridge, and at the first sight can come across just like any other decadent, falling-apart and rusty building in Odessa. However, if you find the right angle, the building looks like it has only the front wall… and nothing else! This awesome optical illusion is what gave the House its multiple names – Devil’s House, Witch’s House, of Flat House.
