The Church of Sant’Agostino in Città Sant’Angelo, together with the convent complex behind it, stands at the highest point of the hill on which the village is situated. It was probably founded before the 14th century, on a site that had previously been home to a religious building dedicated to Santa Maria. In 1314, King Robert of Anjou granted the church and the surrounding land to the Augustinian Order, thereby facilitating the construction of the convent.

During the 18th century, the building was completely transformed, making it difficult today to reconstruct its original medieval appearance, due to the plaster cladding and the rich stucco decoration. Only a few elements of the older structure remain visible, such as part of the bell tower with its characteristic flying buttresses and a section of wall along Strada Minerva, corresponding to the sacristy area.

The interior consists of a single nave, flanked by four side altars decorated with stucco work and bas-reliefs by Alessandro Terzani of Como, which contribute to the church’s elegant ornamentation.

The façade, as is the case with other churches in the village, is situated on the long side of the building and was designed in 1798 by Santino Capitani. Striking in appearance, it is punctuated by four pilasters and divided by an entablature with a projecting cornice; at the centre is a niche housing the statue of the saint, completing a harmonious and solemn architectural ensemble.
