A large section of the roof of a gallery associated with the ruins of Nero's Golden Palace has collapsed. See http://news.yahoo.com/s/ap/20100330/ap_on_re_eu/eu_italy_nero_s_palace
Umberto Brocoli, an official from Rome's artistic superintendence, shrugged off the incident as inevitable given the building's age: "There are 1,900 years of history," Broccoli said. "Two months of rain are not responsible for this. It would have happened anyway."
Fixing the damage is estimated to cost 800,000 Euro and will take one year.
in any event, stories like this one again suggest that Italy already has its hands full taking care of its major cultural monuments and efforts to extend State control to common artifacts, like coins, will not as is claimed help support their study, display and conservation.
