Inspired by Vipes post I have been doing a little research this morning and I found an article from the Independent, here:
...the site of Pissarro's most famous London painting has altered beyond recognition. Lordship Lane Station was painted from a railway footbridge on Sydenham Hill. The bridge remains, but the tracks have gone, and the cutting has become a forest. In the painting, you can see for miles. Now you can barely see from one side of the footbridge to the other.
This would suggest that you can still stand where Pissarro stood on the footbridge in Sydenham Hill Woods, looking towards Dulwich.
I think Pissarro was as bourgeois as any other residents of the fashionable smart new suburbs of London. His big regret seems to have been that he did not have enough money to live in a bigger house in London.
