Rebuilt probably on the site of an older castle, it is first mentioned in a bull published by Gregorious VII in 1074.
The enclosure of the Castrum Novum was fortified around the end of the second half of the 13th C. by Sciarra Colonna. Inside it, in the new chapel dedicated to San Silvestro, is preserved the frescoed image of the Madonna with Child and Saints.
Pope Alexander VI, having occupied the fortress in 1501, equipped it with artillery. Even the village, which from the primitive nucleus that had built up around the castle had grown in size and merged with it, was surrounded by walls and circular defensive towers. During the second half of the 16th C. Sciarra Colonna commissioned the Zuccheri workshop to decorate the “Palazzo”.
Currently the might building structures which enclose the courtyard, now devoid of all purpose, are awaiting consolidation work and some form of reuse that might re-establish the prestige of the ancient Colonna fortress.
