Sant'Egidio is one of the oldest churches in the area, with a Romanesque or even early medieval layout. It was the main church of Civitaretenga, before it became SS. Salvatore: following the 2009 earthquake, however, it has once again become the main church of the town.
The structure is simple, with a single nave and a semicircular apse. The façade is late 15th-century: the portal has a lunette with traces of frescoes, while the architrave is actually a reused Roman epigraph, which can only be seen by looking up immediately at the entrance. Upon entering, one is struck by the simplicity of the building embellished by the late 14th-century frescoes of the apse basin, with Christ Pantocrator surrounded by angels, prayers and musicians. The beauty of the frescoes is further enhanced, on a historical rather than aesthetic level, by a chronicle of events between 1478 and 1480, graffitied without particular care carving into the pictorial layer of the frescoes: years that coincide with the raging of the pestis maxima of L'Aquila.
