Took the tour of #HighgateCemetery in #London with volunteer guide Richard. (amazing tour, highly recommend)

Interesting to see this marble lion headstone for George Wombwell #menagerist was still white 100 years after being placed, but in the past 57 years has turned almost black and is unrecognizable as marble. #marble #erosion
