Founded in the 9th century on a hillside on the right bank of the Vomano river valley, the church was part of a Benedictine monastery dependent on that of San Clemente in Casauria and established by Ermengarda, daughter of Emperor Ludovico II. Partly the result of the restorations of 1926, the building still dates from the 12th century reconstruction.
The façade made of white stone blocks and bricks features a beautiful architraved portal with a full semicircular arch, always in stone carved with spirals in classical patterns and dated 1108. The interior has three naves ending in apses. The central one is dominated by the ciborium, perhaps the oldest in Abruzzo, with dense stucco decoration, dating from the mid-12th century and signed by the master Roberto di Ruggero. Below is an altar table whose antependium is a precious inlay of marbles and crushed terracotta.
