What we think we see isn't always what is truly there. In the OP ART Museum you can experience what it's like to be misled by your own eyes and you can admire different kinds of optical phenomena and illusions. Nothing is what it seems, or is it?
You'll find the museum on the top floor of bookshop Selexyz/Scheltema. More information about the opening hours is available on the website.
Important notice: due to relocation OP ART is temporarily closed.
