Copper turns green after a while because of weathering and corrosion.
It is in general the Oxygen in our atmosphere that bonds with the copper, forming a protective layer of "green" oxydation or corrosion.
Further information:
Many buildings have copper-roofs. It is a metal that is easy to cut and form. It is also highly corrosion resistant because the corrosion formed also protects it from further corrosion.
Acid rain however is able to wash away part of the corrosion formed. This mean that in highly polluted areas, Copper is not such a good choice.
The Statue of Liberty used to be the iconic copper color.
