Greenwich Park.
From the top of the hill at the Observatory.
This is my favourite view of London without a doubt, the snow makes it even nicer.
The white buildings at the bottom of the hill are part of the Maritime Museum and the Queen's House.
The buildings behind with the 2 domes (Christopher Wren built these before St Paul's Cathedral) are the Royal Naval College.
In the background is Canary Wharf and to the extreme left is the centre of London with its sky scrapers.
