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.

We had a lot of fun! Its a bit pricey but its not that bad. We took about 2 hours because we spent quite some time in the play room. It wasn't crowded at all, maybe 10 people. The staff was very nice. Would recommend a visit!

My wife, Momo, and I came here because it was right next to our hotel (Occidental) and we wanted to squeeze in one more activity for the day. The museum is fun and cute. It makes you laugh and challenges the brain. It does not take long to finish (less than an hour) and is 16 € each. It is not a must-see, but is certainly fun and especially with kids.

It was a nice exhibition with some nice effects, especially the rainfall and the space tunnel. It's not very large, but it's cute.

We stayed with our 5-year-old daughter and had a lot of fun doing the various games, completing the quiz , and in the end we were handed the master title of illusions. The museum staff was very nice and sympathetic.
