A view of the back wall of a controversial museum designed by U.S. architect Richard Meier, after it was painted overnight with the red and green colors of the Italian flag, in Rome, Monday June 1, 2009. Vandals used paint-filled balloons to splash red and green against the white wall of the Ara Pacis museum, which sits on a fascist-era piazza in central Rome, police said Monday. The vandals also left a porcelain toilet and two packs of toilet paper nearby which were removed by authorities.
