As it stood in 1490

What Mesocco Castle looked like in its prime.

Sits atop a small mountain, its irregular pentagonal curtain wall pierced by five towers of varying shapes and heights, including a tall bergfried and a prominent polygonal tower; the walls are coarse grey masonry following the hilltop contour. An inner residential wing adjoins the main tower and forms the inner castle around a paved courtyard; the church of S. Carpoforo with its bell tower stands within the walls. By 1490 low pitched roofs cover the living wing and gun embrasures and cannon platforms are placed on the curtain walls, all overlooking the valley.

Its story

The story of Mesocco Castle.

The Castello ruins at Mesocco are among the largest in Graubünden, their walls and towers crowning a small mountain above the Val Mesolcina. The castle was originally the seat of the noble von Sax family: by the thirteenth century the local Baron of Sax-Misox ruled the entire valley and controlled a number of castles, and by the fourteenth the family's power had crossed the San Bernardino Pass and reached its peak.

Baron Albert von Sax-Misox was a founding member of the Grey League and the family's future looked bright, but his murder in 1406 began a gradual decline. In 1480 they sold Mesocco and its demesne to General Giacomo Trivulzio; in 1483 the Baron of Sax besieged the castle in an unsuccessful attempt to force Trivulzio to pay. The Trivulzio family held it until 1549.

The interior enclosed a small world of its own: the count's family and his soldiers lived alongside armouries, a foundry, a bakery, a dairy, a cistern and a charnel house, with a church inside the walls. The ruin is a Swiss heritage site of national significance.
