Ancient and Modern London

I went on a tour of Roman remains below Billingsgate, seeing the underfloor heating and a bath house. Then back to the horse sculptures at Vauxhall, half-deep in water today. Sadly one has already been marred by graffiti. And despite warning signs many people were on the foreshore to get a closer view. The yellow vessel is a 'duck boat', which runs on the road and the river!!
