Sorry for being late. There was some sort of explosion on campus so I figured I'd go check that out.
When I was studying in London, I lived just down the hill from Alexandra Palace. It was an awfully cool building, and it had an even better view of the greater London area. Originally completed in 1873, Alexandra Palace was intended as a public gathering space, and was initially supposed to be called The Palace of the People until Alexandra of Denmark married Prince Edward. On May 24th, 1873, the palace and the park were opened up to the public in a ceremony.
... Awkward. Fortunately it was quickly rebuilt and reopened in 1875. Notably, Alexandra Palace was the home of the first regular high definition television service in 1936. I'm not entirely sure what they classify as high definition, but maybe they just mean a regular television broadcast. Anyhow, it's a pretty neat place. There's even an ice rink in there.
