The law society library zinc has gone that strange yellow/rusty colour because it has been used in a sheltered area where it can’t be washed clean of atmospheric pollution by the rain – I’d assume that a good cleaning would bring it back to the proper grey colour but in general it’s a fairly poorly maintained building. Zinc remains grey provide it’s used in places where it will weather naturally.

But It has only got that pattina colouration on the portion which is shaded from the sun.
