Hornsey, North London.  Another example of Victorian opulence, built in 1873 as a rival to South London's Crystal Palace. Famous for its connections with Marconi and the BBC - the mast on the right is still used for tv signals, and for two disastrous fires, one just months after it opened and another in 1980.
