House of illusions

The House of Illusions is a museum of fun and educational experience, where you can test the limits of your perception. Inside, relativity is something that you experience literally. The illusions provide a different experience of space and everything you think you know about it.

The museum offers around 70 exhibits, optical illusions and holograms. Smaller installations such as the Mirror of Truth, Rubin's Vase, Albert Einstein's Hollow Face, etc. are placed everywhere. Photos and holograms change, appear and disappear in front of your eyes.

The museum's attractions include the following rooms of illusions:

  • Anti-gravity Room, where everything seems to defy the laws of gravity.
  • Rotated Room, where your reality rotates through 90 degrees.
  • Infinity Disco Room, where fun and dance stretch into infinity.
  • Ames Room, where you grow taller or smaller.
  • Vortex Tunnel, where everything appears to rotate and you fight for balance.
  • Playroom with didactic-logical games and enigmas.


Open every day from 9 a.m. to 9 p.m.
