The religious institutions

             From the year 1053 the city becomes an Episcopalian venue immediately subject to the Santa Sede with the first bishop Azzolino; it numbers among the pastors of its Church prelates of high cultural prestige among which Guitmondo II, perhaps among the most eminent men, theologian, author of the treatises on the Eucarestia, on the Confession, on the SS. Trinità.
            Aversa besides boasted the prestigious School of the Cathedral where the most varied disciplines were taught, specially those of law, legislative and grammatical, so that Alfano, one of the most famous pupil of its time, later archbishop of Salerno, adressing to Guglielmo friend remembers the old period of studies that now has passed by,"....in that city, all filled with philosophical contests" (Giorgio Falco, Alfano di Salerno, 1912) and in exalting "the virtues and the doctrine of bishop Goffredo (1059-73), doesn't hesitate to exclaim:

Aversum studiis, philosophos tuis
In tantum reliquos vincis, ut optimus
Dispar non sis Athenis.

 Besides Alfano himself remembers a famous Guglielmo, grammatic aversan, e praises him through these lines:

Cui tot Aversæ studiis ad auctum
Oppidum censum dedit atque dulcis
Culmen horis.

            Beyond to the important Episcopalian venue that linked the most ancient dioceses of Cuma, Literno e Atella, the town numbers the ancient coenobitio centre of San Lorenzo, even it immediately subject to the Santa Sede, that, with the feminine coenobitic centre of San Biagio constituted important points of monkish reference of prestige and boast in Italy. The Convent of San Lorenzo is known also for the captivity and staying of famous men: Pope Urban II, St. Anselm of Aosta, Antipope Alberto of the Sabina, called even of Aversa, gone to the pontifical seat during the schism against Pascal II who remained there imprisoned from 1101 till his death.
            The construction of the fourth city wall and the absorbment of the burgh of San Biagio goes up to 1382. The ancient burgh of Savignano, of which we have already news from the IX century, will be embedded only later while that of San Lorenzo will be always out of the walls.
