Strike the pose, snap the photo, upside-down! Only your imagination is the limit. • Head on a plate - Are you hungry? We have prepared you favorite meal, your friends head!

They trick our brain and our senses into believing what we are seeing is the truth. Our brain gets tricked by illusions, usually by receiving too much detailed and different information at once so it shows us a different truth from the one that really appears on paper. Each brain works differently (to a degree) so every person perceives Illusions differently. Do you want to know how you will experience our illusions? When can I visit the House of Illusions? We are open every day from 9AM till 10PM. Pick the time that suits you best and explore the world of illusions. Be sure to bring your camera or smartphone with you. You will make some great photos that you will want to share them with your friends. Where can I find the House of Illusions? In the center of Ljubljana on the Congress square 13. See you in the world of illusions – see you in the House of Illusions.

Dennis was great as we walked in and he explained all the details to us and offered the secret puzzle game to us. We all had a wonderful time and our daughter (12) loved it.
