The Taj Cape Town has very striking wrought iron work on the Reserve Bank building. The grills, that protect the window, were thought at first glance to be made out of 100% wrought iron. But, upon further investigation, we discovered that the urn-shaped top of each grill was in fact bronze. It was just covered in years and years of dirt.
