The British Museum
Great Russel Street

The British Museum. Yup, the name says it all...what's special about this museum is that it epitomizes the whole British esthetic --- the fads and trends, the eccentricities and oddities, the ideals and aspirations of the past couple hundred years or so. So you get gorgeous examples of artifacts (they have the Elgin Marbles and the Rosetta Stone), but also some weird stuff like stuffed mermaids and a creepy number of Egyptian mummies.
Tiles with stag and doggies, France, 1200-1300.
Seriously, this museum is massive and you'd need a few visits to take it all in. It's in a very gorgeous, old space. We had a whirlwind two-hour tour and it of the little we saw, it was a lot to take in. Donations, of course, are welcome here. This is on our must-revisit places next time we go back.
