The city is tightening the rules for advertising on Romes most famous monuments and buildings. Under recent new regulations the city will once again try to enforce the ruling that there can be only one structure under wraps in the same zone or square. Secondly, if work on the monument or building is suspended for more than seven days the grant will be revoked and the advertising will have to come down. The regions superintendent for the national heritage, Luciano Marchetti, said this was a key step toward protecting the urban landscape and a means of preventing bogus restorations or work deliberately prolonged to increase advertising revenues for the sponsor. Money gained from advertising on monuments is a way of paying for the expensive restoration work involved.
