Externally the abbey appears as a low building with Sicilian roof, rectangular windows and doors framed in lava stone. In the center of the paved courtyard there is a well in masonry of octagonal shape with elements in stone of decorative crowning, with an octagonal perimeter footboard cordoned off. The building complex, in the state in which is now, gives only a vague idea of what was the original structure of the abbey's church, of the capitulary hall, the guest-rooms and the monastery cloister. The news concerning the collapses due to the frequent earthquakes (among which the devastating one of 1693) make us suppose that what we see now corresponds in minimum part to the initial situation. Is also likely that the most solid disposition of volumes of the monastery - called Nelson Duchy -, is the standing one arrived up to us in better conditions as, once passed to the Nelson, it was reclaimed and used as residence. All the other structures instead remained bound to the management of the very vast agricultural fund. All the rooms, organized around the central courtyard, were used by the Nelson as deposit, cellars, stables and granary. In this last one, recently turned into a very big hall with a single wooden covering supported by trusses (it became a study and congress center), interesting remains of Santa Maria's ancient church were brought to light (between which the apse). The planimetric scheme of the premises and some architectural elements of the courtyard make think that the abbey was organized as a ring-like plant, around a central courtyard (accessed from the principal entry courtyard to the Duchy. Is clear also that the visible ancients turret masts of Norman epoch that were protecting the abbey, and still visible, was part of a building complex of remarkable proportions and importance. Maybe of the turret masts, the one facing south-west must belong to the original period; it has a solid and compact structure with vertical slots for sighting and defense. The two guard turrets
on the river facing north-west and north-east must be of a more recent period. They have a cylindrical disposition of volumes with raw, very thick masonry, crowned by a battlement slightly jutting out on a frame of terracotta elements. |
