The monastic complex of St. Augustine is located in 200 metres East of the Royal Palace Reggia di Caserta in Caserta on Largo San Sebastiano. Previously this building belonged to the monastery, but today it is a Museum.

The order of Augustinian appeared in the Kingdom of Naples in the 13th century – he immediately received the support of king Charles II of Anjou, who even gave to the monks the privilege of the grain trade. In 1441, the year of Caserta was built the first building of the monastery of the foothills, to which were later added additional rooms for the monks and a courtyard with a colonnade. However, in 1652, the year by order of the Pope, the convent of Sant'agostino was closed and the monks were dispersed. The then Governor of the count of Caserta Acquaviva handed over the building to the religious complex of the Dominican order, who founded the monastery school of music for girls from poor families. In the 18th century with the support of king Charles III of Sant'agostino is booming: in place of the old Church from the 15th century was built a new one, on a project which, probably, worked as court architect Luigi Vanvitelli, and in 1767, the year it was enlarged and re-decorated the building of the monastery. The current neoclassical façade of the Church was made in the mid-19th century. Inside it has a single nave with barrel vault. On the side walls there are niches with altars and paintings by 18th-century artists of the Neapolitan school. On the left wall is preserved fragment of the frescoes of the 16th century depicting Mary Magdalene. The main altar of the temple was made in the 19th century. I must say that today the Church is dedicated to Saint Sebastian, the patron Saint of Caserta. And the building of the monastery after the restoration has opened a cultural center consisting of a Museum of modern art, Museum, festivals, customs and traditions, library and drawing classes.
