Is Kunsthistorisches Art Museum in Vienna the world's best museum?

I've been there and while you won't get any argument from me, I prefer the Musee d'Orsay in Paris.

The Philadelphia Art Museum certainly has an impressive collection of historic and modern art, including Monet, Manet, Van Gogh (Sunflowers!), Whistler, Jasper John, Titian, etc. The only artist I could think of that was not in the museum was Leroy Neiman. :-)

Tough question. I put it in the top 3, at the lease, more than anything because of the Brughels. My dream is to go back there and stay in the room with them all day.

The National Museum in London and National Museum in DC are also tops on the list, as is the Rijksmuseum in Amsterdam and the major museum in Munich.

The only major museums of Western Art I have not seen are in Madrid, Russia and Rome.

I suspect I would also like the Tate. I've been to the old Tate (The Fairy Feller's Masterstroke is a hoot), but not to the new.

When I go to a new city, the first thing I do after the essentials have been taken care of (hotel, food, etc.), I head for the art museum. A couple of others I have liked: Moma in LA; the Orsay; the National Portrait Museum in London; the Uffizi; etc.

I respectfully disagree with OP.

Musee du Louvres is one of the most popular museums in the world.
You cannot visit the Louvres in one day, and see everything there is to see in one day. Thats how big and interesting Louvres is.

How come this Viennese museum isn't as well known as the Musee d.Orsay or the Louvres?
