The interventions promoted by Charles I of Anjou date back to 1277, to be recognized in the ogival vaulted rooms adjoining the oldest part of the structure corresponding to the rectangular-shaped keep. To the Counts Della Ratta, feudal lords of Limatola from 1420, are ascribable the interventions on the outermost walls and restructuring and extensions implemented in some rooms on the stairs and loggias, in Renaissance taste.

In the second decade of the 16th century, Francesco Gambacorta and Caterina Della Ratta carried out interventions on the defensive structures and on the Palatine Church of St. Nicholas, which, however, retains its original Romanesque portal. During the Renaissance, major renovations transformed it from a military dwelling, of which it still retains some features such as the City Wall interspersed with towers and the Scarpata up to the height of the cornice, to a stately home.
