It was designed by a Norwegian firm called Snohetta in 2004. It's a very cool building. Actually I'm enamored of the shell more than the insides, which don't seem to correlate much. There's a Guggenheim thing happening on the interior - in wood - and a floaty, white marble-y thing happening on the exterior.
In all, it's a lovely place to wander around, and to then sit and drink coffee while sketching.
