Hop off at Greenwich pier and take a short walk to the Royal Observatory. Originally built for the Astronomers Royal and set in a charming historic building, the Observatory now boasts a modern planetarium, the Great Equatorial Telescope and of course fantastic views of London from Greenwich Royal Park.
