Castello di Monte San Giovanni Campano

The Castle of Monte San Giovanni is a historic medieval fortress located in Monte San Giovanni Campano within the Lazio region of central Italy. Originally constructed in the 11th century, the structure stands as a remarkable example of early defensive architecture. The site is distinguished by two primary towers, one quadrangular and one pentagonal, the latter being an unusual design feature for castles of this era. These towers remain largely unmodified, showcasing thick walls measuring 3.5 meters, complete with bartizans, double-width patrol walks, and internal communication passages. Although it was once part of a much larger complex that included five towers, a ducal palace, and enclosing town walls capable of housing over a thousand defenders, only fragments of this grand structure survive today.

Historically, the castle holds significant fame for two distinct events. It is renowned as the location where Saint Thomas Aquinas was imprisoned by his family between 1240 and 1242 in an unsuccessful attempt to prevent him from joining the Dominican Order. The specific rooms where he was held are located at the base of the rectangular tower and have been preserved and restored, now displaying a 16th-century Neapolitan-style triptych. Furthermore, the fortress marks a pivotal moment in military history as the first fortification ever breached by portable artillery shelling. In 1495, during the French conquest of Naples, King Charles VIII's army bombarded the supposedly impregnable castle, causing it to fall after just eight hours. This event led to a tragic massacre of the inhabitants and signaled the end of the castle's reputation as an unconquerable stronghold. Today, the site serves as a historical monument preserving these layered narratives of religious history and military evolution.
