The monastery of S. Liberatore was governed by Montecassino and run by the Abbot’s rector. Built in 1007 by the monk Teobaldo, it was re-constructed in 1080 by Desiderio, Abbot of Montecassino who sent artists and masons to start a school which undertook building in Abruzzo.
The façade design recalls Lombard style and it has in the upper order three simple monoforium windows, and in the lower order three portals typical of the most ancient kind of Abruzzese Gothic.
The interior is a basilica layout: a nave and two aisles cadenced by seven round arches resting on rectangular pillars. The ceiling has been rebuilt with exposed wooden trusses.
The remain of a polychromatic geometric composition, made by marquetry craftsmen in 1200, decorate the floor of the central nave. Before its restoration the apse dome had two superimposed frescoes, which have been separated.
The more recent, dated around 1500, was transferred into several panels and depicts the monk Teobaldo in the act of donating the church. The fresco left in the place dates back to the 12th century and traces of saintly figures are visible. The square-base ambo rests on four plinthless columns and bears a striking resemblance to those of S. Clemente a Casauria and S.Pelino a Corfinio, both late 12th century.
