Castello di Strambino, Medieval castle in Strambino, Italy.

Castello di Strambino is a castle complex made of several buildings from different periods. Its oldest core is the 11th-century Arduin castle; the southward extension is the 15th-century Gothic castle, and the palazzo built further south on the old fortress's ramparts forms the 17th-century lordly castle.

The castle is first mentioned as Castrum Strambini in a 12th-century document, when it most likely depended on the bishop of Ivrea. It underwent numerous modifications over the centuries. In 1797 it became allodial property of the counts San Martino, who left it in inheritance to Don Bosco; the marquis Scarampi di Villanova bought it in 1870.

The castle's name comes from the Latin Castrum Strambini, recorded in a 12th-century document. The complex grew in stages: the Arduin castle of the 11th century, the Gothic castle of the 15th century, and the lordly palace of the 17th century built on the old fortress's ramparts. In 1797 it became allodial property of the counts San Martino, was bequeathed to Don Bosco, and was bought by marquis Scarampi di Villanova in 1870.

The complex is made up of separate building bodies from different eras, so a visitor moves from the 11th-century core to the 15th-century southern extension and then to the 17th-century palazzo further south. The oldest part is the so-called castello arduinico; the Gothic section lies south of it, and the seigneurial palazzo stands on the ramparts of the former fortress.

The castle passed by inheritance to Don Bosco before Marquis Scarampi di Villanova bought it in 1870. Its three building phases are stacked southward: the 11th-century Arduin castle, the 15th-century Gothic castle, and the 17th-century lordly palace raised on the old fortress's ramparts.
