AREQUIPA

The city has many colonial-era Spanish buildings built of sillar, a pearly white volcanic rock, from which it gets the nickname La Ciudad Blanca ("The White City").[1] Reportedly, it first acquired this nickname in the colonial era, because most of its inhabitants were Creole of Iberian descent. The historic centre of Arequipa was named a UNESCO World Heritage Site in 2000, in recognition of its architecture and historic integrity.
