When damage to monuments did occur, MFAA personnel worked to assess damage and buy time for the eventual restoration work that would follow. Monuments officer Deane Keller had a prominent role in saving the Campo Santo in Pisa after a mortar round started a fire that melted the lead roof, which then bled down the iconic 14th century fresco-covered walls. Keller led a team of Italian and American troops and restorers in recovering the remaining fragments of the frescoes and in building a temporary roof to protect the structure from further damage. Restoration of the frescoes continues even today.
