Under the deal, UNESCO said it would provide expert advice to the Italian government on how to upgrade conservation.
In November 2010 there was a collapse in the House of the Gladiators which drew criticism from UNESCO and the European Union.
It was followed soon after by a collapse at the famed House of the Moralist, spurring further criticism from international conservation groups.
