Chiesa dei Santi Pietro e Paolo, Baroque church in Sassi district, Matera, Italy.

The Chiesa dei Santi Pietro e Paolo is a baroque church in the Sassi district of Matera featuring three portals with statues of Madonna, Saint Peter, and Saint Paul. Single rectangular windows sit above each entrance, and a square bell tower with geometric balustrade rises at the eastern corner of San Pietro Caveoso Square.

The present church was built in 1218, partly cut into the rock face below the Madonna dell'Idris; traces of the rock church survive in the right aisle, where a niche now holds a statue of San Giovanni da Matera. A total 17th-century renovation added the baroque facade and the bell tower, enlarged the interior with side chapels and replaced the wooden truss ceiling with tufa. A plaque records the reconsecration in 1706, when the bell tower cusp, stucco decoration and a wooden counter-ceiling were added.

The church is popularly called San Pietro Caveoso, a name tied to the cave church once carved into the rock face above the square. The 1706 reconsecration is recorded on a plaque inside. The wooden ceiling panels depict Christ entrusting the Church to Saint Peter, the Madonna del Confalone and the Conversion of Saint Paul.

The church sits at the eastern edge of San Pietro Caveoso Square with direct views over the Gravina ravine. This location at the cliff edge helps visitors understand the dramatic terrain surrounding the old town.

The 13th-century baptismal font in the fourth left chapel was freed from a layer of stucco added over the centuries during restoration, revealing its carved bas-reliefs. The same chapel holds 17th-century frescoes of saints, including Saint Francis of Paola and Saint Dominic, and part of a wooden relief of God the Father blessing.
