The interior of Carignanio palace is seen in Turin, Italy, Sept. 9, 2013. The UNESCO Commitee inscribed the residences of the royal house of Savoy in and around Turin as a world heritage site in 1997, considering that they represent a comprehensive overview of European monumental architecture in the 17th and 18th centuries, using style, dimensions and space to illustrate in an exceptional way the prevailing doctrine of absolute monarchy in material terms.
