London has a lot of two things - pubs and museums. I spent time at both of these types of cultural institutions and learned aplenty.
The British Museum is really a beautiful building (see!) and is chock full of prizes and artifacts stolen from the various colonies that used to be under its rule. Wild.
Here is one that I particularly like that was taken from Easter Island.
And here's a picture of a pub, called the Nag's Head, which contained a different sort of relic all together. A "landlord" ran the place, instead of a bartender, and you didn't tip him, but instead, bought him a round.
