Church of St. Mary of Constantinople

La Church of St Mary of Constantinople of Pietracatella has its origins in the 14th century with a rural chapel in the locality of Puzzoreo, which housed a wooden statue of the Madonna and Child. The chapel fell into ruin and in the 1690 the cardinal Vincenzo Maria Orsini (later Pope Benedict XIII) ordered its closure, moving the image to the church of San Rocco. It was Orsini himself who gave it the title of St. Mary of Constantinople in the 1705consecrating it in the 1713.

After several restorations, it was decided in the mid-19th century to build a new, larger church, based on a design by the master Andrea Minchillothe present three-aisled building was consecrated in 1893the façade completed in 1874 and the bell tower in the 1939.

Inside is a statue of Our Lady of Constantinople (1695, by Giacomo Colombo), a high altar in polychrome marble with cherubs, six minor altars decorated by local masters and an 18th-century organ by Gennaro Severino. The façade was enriched with stained glass windows in the 2000 and, since 2023, the church is Diocesan Shrine dedicated to Workers' Victims.
