One of the key places in Naples if u love modern art. I have been there a couple of times over the last 6/9 months, to see Escher first, and then Joan Miró. Both exhibitions were very well arranged and provided a comprehensive overview of both artists. Specifically, I found out something I didn't know about Miró, e.g. that his very peculiar artistic expressions, were not limited just to canvas, that sometimes he liked to burn to create "special effects", but also to collage, technique where he utilized the most different materials. The exhibition should still be on through February I guess, so please go see it, it's worth the money. I also enjoyed Escher, but the fact that I had already seen him years before at the Chiostro del Bramante in Rome, didn't give me the same magic as with Miró. Currently, besides Miró, they also have a Banksy and more artists on display, in case u, like me, enjoy street art. I'm giving 4 stars rather than 5 because 1) differently than in the past, either time I went over the last year, payment by ATM or credit card wasn't allowed, and 2) I would definitely recommend opening up a coffee bar in the lobby, where people could sit down and relax after visiting the different art exhibitions.
