"Visitors to this turreted riverside castle enter a thousand years of history filled with cultural significance (but go early to avoid lines to see the crown jewels). Tudor fans can view the spot where Anne Boleyn was beheaded and the kinds of instruments used to torture Guy Fawkes after the failed plot to blow up Parliament. Statues of the exotic animals that once lived here in a menagerie—from elephants to polar bears—help visitors imagine the pomposity and surrealism that the Tower must once have represented."
