San Pietro ad Oratorium Abbey

San Pietro ad Oratorium is the name of a Romanesque-style Roman Catholic church, and formerly of an adjacent Benedictine monastery, now in ruins, located on a rural mountainside near the banks of the Tirino river, about 6 km from the town of Capestrano, in the region of Abruzzo, central Italy.

Chronicles suggest that some church structure might have been present by the 7th century, but the original abbey was commissioned in AD 752 by the Lombard king Desiderius and made subservient to the monastery of San Vincenzo al Volturno.

In 1117, the church was consecrated by Pope Paschal II and had acquired more independence and wealth as an abbey.

On the Romanesque portal were added two marble reliefs with the figures of David and St Vincent of Saragossa.

The walls of the central apse support a remarkable 12th-century fresco depicting Christ among the twelve disciples, above a register with the Twenty-Four Elders from the Book of Revelation.
