"It is located in Piazza Azuni, proceeding along Via Marconi towards Piazza Sant'Elena. Its construction dates back to the 11th century and was originally in Romanesque style but was later rebuilt in the late 13th century. It features a simple gabled façade and a bell gable at the rear. The interior has a single nave with a barrel vault and a chancel with a cross vault. There are only three chapels to the right of the entrance, which are also interconnected. Particularly noteworthy is the wooden altar in the chancel, dating back to the early 17th century. Also to the right of the nave is the entrance to the sacristy, from which, going towards the old convent, you can see the remains of the original Romanesque apse. Entering the small park behind the church, you can see the new rectangular apse from the late 13th century.
The building is consecrated."

"The church of Sant'Agata is located in the village of Quartu Sant'Elena, a short distance from the parish church. The Romanesque churches of Santa Maria di Cepola and San Pietro di Ponte (attested among the possessions of San Vittore di Marsiglia) and the country church of San Forzorio, near the eponymous pond, remain within the municipality. The site would correspond to the ancient Quarto Josso; the local name of the area (su Idanu) suggests its identification with the "domestic" of "Suvaydanu," included among the possessions of the Victorine monks in 1338. The current building is the result of numerous renovations, without documentary evidence; during the latest restoration, data was recovered that will allow a critical reinterpretation of the construction phases. Large sections of the walls of the arched sides date back to the Romanesque single-nave layout, dating back to the second half of the 12th century; Gothic interventions in the first quarter of the 14th century led to the demolition of the semicircular apse, which was rebuilt as a
quadrangular chapel (northeast). The facings are made of medium-sized limestone blocks, carefully cut and installed. The northern side features a single-lancet window with a double splay and a sloping sill. Along the terminal are semicircular arches with double architraves, perhaps recomposed during the
14th-century work, which on the other side and in the apse resulted in both the reuse of the original elements and the insertion of small pointed or trefoil arches. The quadrangular apse has a cross vault divided by four ribs and, like the sides, a single external section between wide corner pilasters. It features a light
(much altered) with a pointed arch and a brow on very eroded corbels."
