Napoli before they die.
When these friends prepare for their trip to one of the roots of the classic civilisations they seek out Wikipedia for information. Arguably it is in the macro economic interest of Italy to provide them with superior articles and magnificent illustrations.
It is therefore astonishing to learn that Italy cannot take part in Wikipedia loves Monuments because the state is said to have the copyright on all of Italy's monuments. Some will argue that we cannot have photos of Italian monuments on Commons. Others will argue that the swarms of tourists who descend on Italy are exempt from such Mafia practices. As monuments are monuments for a reason, it is reasonable to expect to find illustrations in images that are out of copyright.
It is likely that these illustrations may need as much restorations as the buildings that are still standing. This is something we can certainly do as Wikipedia loves Monuments.
