The Italian fashion house Fendi has announced that it will provide €2.5 million for the restoration of the Quattro Fontane fountains at the intersection of Via del Quirinale and Via XX Settembre, as well as Fontana di Trevi as previously reported.

The official announcement came on 27 January during the bi-annual AltaRoma fashion week which is chaired by Fendi president Silvia Venturini Fendi. The €2.18 million restoration of the Trevi is part of “Fendi for Fountains”, an ambitious plan that would see the fashion firm sponsor the restoration of some of the city's best-loved monuments.

Fendi has already signed a deal with Rome's heritage authorities for the Trevi fountain restoration which is expected to begin by the summer – once the tender for works has been awarded – and be completed by 2015.

Work on the Trevi will focus on the façade after fragments of laurel leaves to the left of the baroque fountain became dislodged last June following the previous freezing winter. The fountain, which dates to 1732, will not be covered over during the restoration process however.

By contrast the €320,000 intervention required for the late-Renaissance Quattro Fontane monuments will be more straightforward and quicker than the Trevi project.

Comprising the rivers Tiber and Arno, and the gods Juno and Diana, the fountains have become blackened by smog and neglect, and require a substantial cleaning rather than a full-scale restoration.
