Not far away from my window is a big mast.

rising above the trees, and giving the impression HG Wells fiction is actually real and London has been invaded by contraptions from Mars. 

This is in fact the ghostly home of the BBC

Alexandra Palace was originally built as a North London 'People's Palace' very much like Crystal Palace south of the river and opened in 1863.  It became the BBC's home in 1936.  While no production takes place there any more, the antenna does still broadcast to your radio (though probably not your TV anymore).

While the Palace is in a sad state of repair, it still has wonderful palm houses and hosts concerts.  Sometimes there are fireworks.

It's a comforting sight when I go past it on the train or see it from my window and it makes me feel at home. 

Flickr has all sorts of pictures, and with CC attribution licenses you don't worry about breaking the law.  It may take a little longer to find what you want than a google image search, but it gives you piece of mind and spreads willing photographers work to audiences who wouldn't otherwise see it.
