The monastic citadel of SS. Salvatore at Goleto began with this first nucleus starting in 1133 by Guglielmo, who had received the land as a gift from Ruggero, the Norman lord of nearby Monticchio (today ruins remain on a hill between Sant’Angelo dei Lombardi and Rocca San Felice). Guglielmo built the original church with the apse facing east; he leaned the roof slopes against the remains of the mighty Roman-era mausoleum, probably using it as a bell tower; there was abundant stone from the old Roman settlement. If you look up to the right, you can still see interlocking cut of the roofing today. Immediately after the original church, the female convent was built to accommodate a community of nuns where the supreme authority was represented by the Abbess; finally, the male convent was built to house the monks responsible for the liturgical service and the care and maintenance of the various abbey buildings, as well as the cultivation of the surrounding vast lands. The two convents, each with its own cloister, had as their fulcrum the church of SS. Salvatore (today we are left with the remains of its apse). In all likelihood, already at the death of the holy founder, which occurred on the night between 24 and 25 June 1142, a first reconstruction of the original church began, which later hosted the remains of S. Guglielmo in a ciborium placed on the right side, near the altar. You can see what remains of the ancient ciborium by visiting the Museum.
