History

The Castello di Pereto stands on a hill on the slopes of Monte Forcellese in Pereto, Italy. This fortress was originally built by medieval inhabitants to oversee the surrounding plains and control the ancient Roman road known as the Via Tiburtina Valeria.

The earliest construction at the site dates back to the early 10th century when Berardo dei Marsi, a local nobleman, established a tower that later formed the core of the castle’s keep. In the latter half of the 11th century, the castle grew in importance as it became the home of Rainaldo, Count of Marsi. After Rainaldo’s death during the First Crusade in 1093, his widow Aldegrima left Pereto for Oricola and transferred ownership of the castle to the influential Abbey of Montecassino. This ownership was officially recognized by Pope Urban II in 1097 in a papal bull confirming the Abbey’s possessions.

By the mid-12th century, the castle had entered a period of renewal under the De Ponte family. Significant expansions took place during the reign of the Holy Roman Emperor Frederick II, with further additions in the 14th century that included two new square towers and connecting fortifications, defining the castle’s enclosure. At the beginning of the 15th century, the Orsini family took ownership, but their tenure was likely disrupted by a major earthquake in 1456 that caused widespread damage in this part of Italy.

Toward the end of the 15th century, control passed to the Colonna family, another influential noble lineage. In the 19th century, specific structures within the castle, such as the northern tower, came under the use of the Maccafani family. This tower was sold in the early 20th century to the Vicario family. The castle sustained heavy damage during the 1915 Avezzano earthquake. Restoration work began several decades later, led by Aldo Maria Arena after his purchase of the site in 1966. These efforts were notable for their success and quality, earning a prestigious recognition in 1982 from Europa Nostra, an organization dedicated to cultural heritage preservation.

Remains

The Castello di Pereto features a robust medieval layout characterized by a fortified enclosure with three main towers connected by defensive walls. The construction primarily employs stone masonry typical of the medieval period, designed to offer both protection and strategic vantage points.

The central and oldest structure is the main keep, or bergfried. It has a roughly square base measuring about 11.7 meters on each side and rises to 27 meters in height. Inside, the keep is divided into five levels: the ground floor originally functioned as guard quarters, storage spaces, and prisons; the first floor housed the justice hall, where local legal matters were handled; the two middle floors were living quarters for the lord; and the uppermost floor served defensive purposes, acting as a lookout point over the surrounding landscape.

To the north of the main keep stands the second tower, smaller with a square layout of 6.6 meters per side and reaching 24 meters tall. This tower also comprises five floors internally, though details about their specific uses are not documented. A third tower is located to the southeast, standing 16 meters tall on a base of 4.6 meters square. Unlike the other towers, it is not divided into floors and seems to have functioned both as part of the connecting fortifications and as a lookout post.

The castle’s curtain walls vary in length and height but collectively form a defensive perimeter. The southwest wall is 23 meters long and 15 meters high, featuring the main entrance near the keep. The eastern wall runs 24.5 meters and stands 13 meters tall, while the northern wall measures 22.4 meters in length and is 14 meters high. Atop these walls is a patrol walkway known as a chemin de ronde, which allowed guards to move between towers while monitoring the surroundings and mounting defenses as needed.

Over time, these structures have undergone periods of expansion, damage, and restoration. Today, the remains present a strong sense of the castle’s medieval military architecture and its historical role controlling the region.
