The Corridor is an elevated enclosed passageway connecting the Palazzo Vecchio with the Palazzo Pitti, crossing the Ponte Vecchio.
It was built in 1565 after Florence’s then rulers decided they wanted to move freely and secretly between the seat of city government and their private palace.
One piece of graffiti inscribed on the monument reads ‘Dks 1860’, an indecipherable motto.
Florence Mayor Dario Nardella condemned the “shameful act of vandalism” and announced an immediate inquiry to “identify these despicable individuals in order to punish them appropriately”.
He stressed that those who damage cultural heritage “commit a very serious crime”.
Culture Minister Gennaro Sangiuliano said those guilty “must understand that even a small scratch will henceforth be prosecuted”.
