After decades of deterioration, the Puglian rock-hewn churches, including San Pietro Barisano, needed major restorations before they could function again and support congregations. World Monuments Fund placed the rock-hewn churches and the city of Matera on the Watch in 1998, hoping to raise awareness for the sites and their conservation needs.
In 1999, WMF secured a grant that contributed to the funding for the complete restoration and conservation of San Pietro. The main altar was cleaned and consolidated, as were the delicate frescoes that cover the walls of the chambers. Whenever possible, missing pieces of moldings, reliefs, and other adornments were reconstructed from photographic archives or surrounding fragments.
