5 o'clock
as long time viewers will know, i've taken this picture before, but it always makes me gasp when i walk past it. It's on the corner of the Treasury building on Whitehall (on the corner of Parliament Square and Parliament Street [see here] as you walk away from the river)
I'm quite impressed that they managed to get Big Ben [1] through a sash window without leaving any apparent fold-lines.
[1] Yes - I know that Big Ben refers to the bell but I can't remember what the tower and clock is called.
st stephen's tower i think. it's all down with mirrors
