Certosa di Trisulti
A charterhouse founded in 1204 by Pope Innocent III in the forest of the Monti Ernici, held by the Carthusians until 1947 and then by the Cistercians of Casamari. A national monument since the 1870s with an 18th-century pharmacy and a library of some 36,000-37,000 volumes, it is now run as a state museum site; in June 2026 the regional administrative court (TAR) rejected the last appeal of the Bannon-linked Dignitatis Humanae Institute over its canceled lease, which the press reported as the apparent end of the dispute.
FAI's page on the site says the church and the old pharmacy are damaged by water infiltration and that the roofs need urgent restoration. The Ministry currently has two small Art Bonus appeals open, both almost unfunded: conserving the 13th-century lion sculpture with its pillar and stair wall, and restoring a Filippo Balbi canvas of Carthusian saints.
Before you act. The two open appeals are small and concern a sculpture and a painting. No costed appeal for the roofs was found, although the Italian heritage trust FAI says they need urgent work. A larger donor would need to deal directly with the Ministry of Culture.

Milan, Italy
The roofs of the abbey church are degraded: tile courses are irregular and water is getting in and damaging the frescoes inside. The monks' official Art Bonus sheet prices the roof works at just over EUR 1.02 million, of which about EUR 205,550 has been donated; a second open project restores the 16th-century entrance tower.
Asciano, Italy
The monks are renovating the guest house (Casa Ospiti) to meet safety rules: removing architectural barriers, new visitor toilets and a bathroom for each room. The Art Bonus sheet lists a EUR 400,000 project with works in progress; spending so far has outrun the donations received.
