The museum, dedicated to the work of Victor Vasarely, the founder of Op-Art, costs about €6, with an additional small fee for taking photos, bringing my total to around €7.50. It presents an extensive collection of his works, known for their geometric shapes and optical effects. The museum itself is very exciting if you enjoy this type of art. I took many pictures and really liked it. Depending on how busy it is, you might have the rooms to yourself. It was quiet when I visited, but there was a small line at the ticket counter when I left. I was there around 4:30 PM and spent about 30 to 45 minutes in the museum. A fascinating visit for those interested in modern art and optical illusions.
