Castello di Aymavilles

Aymavilles Castle rises on a hill at the entrance to the Cogne valley, with four round towers, white façades and loggias. Built and altered across several centuries by the Challant family, it preserves medieval fortifications, later aristocratic interiors and a terraced park.

Why it matters

Aymavilles Castle traces the transformation of a defensive stronghold into an aristocratic residence. The first secure record dates to May 1207. Later generations of the Challant family added towers and expanded the central body; eighteenth-century remodelling introduced loggias and a terraced park. The building’s four towers preserve evidence of its earlier military role.

What to notice

The four cylindrical corner towers have different crowns: two with Guelph merlons and two with Ghibelline swallow-tail merlons. The castle’s later white façades and loggias contrast with the medieval masonry. Inside, the rooms retain painted decoration from the 1840s, including neo-Gothic, neo-Egyptian and chinoiserie styles. The attic preserves fifteenth-century roof timbers, and the terraced park steps down toward the village.

Context and history

Amedeo di Challant added the four towers and a double curtain wall in the early fifteenth century. Around the middle of that century, Giacomo di Challant raised the central body and towers, leaving roof timbers still visible. In the early eighteenth century, Baron Joseph-Félix de Challant transformed the building into a residence, adding loggias and laying out the park. The castle passed to the Region of Aosta Valley in 1970. Restoration began in 2000, and the current museum layout was completed in 2022.
