History
Castello Mirabello is a Roman-origin fortified site in Italy, in the municipality of Chiusa di Pesio, where a Roman mountain position was later incorporated into a sixteenth-century feudal castle. The site occupies Monte Cavanero, a mountain spur above the present municipal center, and reflects successive connections with the Roman Empire, the Marquisate of Ceva, and the Duchy of Savoy.
Before and during the Roman period
Monte Cavanero contains evidence of settlements occupied between the eleventh and ninth centuries BC, during the transition from the Bronze Age to the early Iron Age. Much later, during the Roman period, the mountain spur was fortified, probably to control the road between the Ligurian coast and the Po Valley. A small garrison of legionaries may have been stationed there.
Coins, pottery, and burial remains connect the site with the Roman period. A Roman tombstone was already known in the nineteenth century. The original appearance of the Roman fortification is difficult to reconstruct because its building materials were reused in modest dwellings and later in the feudal castle.
The sixteenth-century feudal castle
Construction of the feudal castle probably began in 1565 on the initiative of Agamemnon III, the feudal lord of Chiusa di Pesio. In 1583, he ceded his fief. His only son, Alberto, entered the Franciscan order, a religious order founded on the teachings and example of Saint Francis of Assisi, and therefore did not continue the family’s dynastic succession.
Decline and modern damage
The castle was gradually abandoned. An earthquake on February 23, 1887, severely damaged the building, and a blizzard in January 1888 caused further harm. During the Second World War, Nazi occupation troops bombarded the castle as an act of intimidation, adding to its destruction.
Work to secure and enhance Castello Mirabello began in summer 2022 through a program agreement between the Piedmont Region and the municipality of Chiusa di Pesio. The intervention forms part of the site’s modern preservation history.
Remains
The castle stands on a shelf slightly below the summit of Monte Cavanero, at the position occupied by the earlier Roman fortification. The surviving structure is built of stone and brick and preserves parts of the sixteenth-century arrangement, including a northeast tower and masonry from the central keep.
Castle layout
The sixteenth-century building had three floors. Its west-facing section was divided into two rooms, while the eastern section contained a hall. The entrance was located on the north side. A spiral staircase connected the floors, and the steps remain fixed in portions of the surviving walls.
Surviving structures
Cylindrical tower
A tall cylindrical tower survives on the northeast side of the castle ruins. Its position and form identify it as one of the principal remaining elements of the feudal complex.
Central keep
A small section of the central keep’s masonry also remains. Traces of a terracotta pipe are preserved within these walls, while fixed remnants of the spiral staircase retain evidence of the castle’s internal circulation between its three floors.
