Located just a hop, skip and a jump away from the Estonian National Museum and its dramatic structure, the Upside Down House will challenge your perception of reality – if it doesn't, we'll be happy to refer you to a very good psychiatrist. For those that aren't quite sure, the whole house has actually been built upside down and all the furnishings have been attached to the walls or ceilings, or floors, or... we'll let you be the judge. While we think it would be quite a challenge to live here (especially using the toilet or having a bath), it's certainly worth a visit. The attention to detail here is fantastic and is the perfect place to take some funky selfies, although most of the situations one can get themselves into here will probably require the assistance of a friend. Oh, and if you think you can handle more dimensional confusion, we dare you to rent a pair of reversal goggles which will ... you got it, turn your view upside down! What will they do in an upside down house? You'll have to discover that one out on your own.
