The Gemeentemuseum Den Haag (English: Municipal Museum) is an art museum in The Hague in the Netherlands. The museum, built 1931–1935, was designed by the Dutch architect H.P. Berlage. It is renowned for its large Mondrian collection, the largest in the world. His last work, Victory Boogie-Woogie, is on display here.
If for any reason you find yourself in Florence, Italy (Firenze in Italian) you should hightail it to the San Marco Museum (Museo di San Marco). No excuses. None whatsoever, you must go. Be aware, the museum is only open from 8:15am - 1:20pm Monday through Saturday. I once arrived at 1:15 and they were not letting anyone in. The door was closed, didn't happen. Be diligent, don't go to the Uffizi first or the Duomo or shoe shopping, go to San Marco! If the Queen's Chips is open on your stroll down Via Camillo Benso Cavour, of course stop and eat those damn fries the last few blocks. Here at Trivium, we like to stop at Bar San Marco, just across the Piazza from San Marco — get a Macchiato, you will need it to handle the awesomeness of Fra Angelico.
