• About 50 minutes inside, the length the museum gives for a typical visit, so it pairs easily with a walk around Monastiraki or Plaka
• No strollers inside, since the rooms are not stroller or wheelchair accessible, so bring a carrier for babies
• No lockers or cloakroom, only a space at reception where bags are left at your own risk, and no food or drink is allowed inside

An interactive museum of optical illusions where visitors step into the exhibits and pose for photos that trick the eye. Kids cross the spinning Vortex Tunnel, test their balance in the Tilted Room, walk through the upside-down Reversed Room, and grow or shrink in the big and small room. Mirror rooms, hands-on installations and puzzle images fill the rest of the route.
