More old and new

I'm heading to Heathrow late this afternoon for a very early flight back to New York in the morning, so I had a few hours to walk around and take some pictures, and I was glad to see the sun was back. It was very windy however, and I'd lost my scarf somewhere along the way, so the trek across London Bridge took my breath away, and not just in the good way. 

Here's an old window in a broken wall nicely framing modern glass.
