Here's my guide to Andrea Mantegna's famous Camera degli Sposi in Mantua Italy. The Camera is a magical room frescoed with illusionistic paintings in Mantua's Ducal Palace. It's a hugely influential masterpiece from the Early Renaissance. It's considered the first trompe l'oeil in the history of painting. For its beauty and uniqueness, the Camerabecame a designated UNESCO site in 2008.
