The chiming of the Big Ben is famous, lots
of clocks (not those digital ones, though) have the same tune. The face is a
lot bigger than it seems. This year it was cleaned by some men who crawled
over it like small spiders.
The guardsmen stand very still
on their horses. That does not seem a very hard task, but next to us are
standing a lot more people. It must take a lot of training to make sure the
horses don't get nervous by those crowds. And the men on the horses, of
course they have to be trained too.
