Castello di Malgrà, Castle and military museum in Rivarolo Canavese, Italy.

Castello di Malgrà in Rivarolo Canavese began as two separate buildings joined by a perimeter wall and a circular tower that still stands. A two-arched portico was added the following century, when the hall walls were painted with religious frescoes. The west wing was restored by Alfredo d'Andrade from 1884 and completed by Carlo Nigra in 1926.

Martino di San Martino, the feudal lord, built the castle between 1333 and 1336. It stayed with the counts of San Martino until the mid-17th century, then passed through several owners and was enlarged over the following centuries. The western wing was restored from 1884 by architect Alfredo d'Andrade, work completed in 1926 by Carlo Nigra. The municipality bought it in 1982.

Since 1993 the Associazione Amici del Castello Malgrà, working with the municipal administration, has opened the castle and led guided tours from May to October. The rooms also host exhibitions, concerts and cultural events, and the park is named after the Rivarolo partisan Dante Meaglia (1923–2007), decorated with the silver medal for military valour.

The castle is open to visitors every Sunday from May through October between 3 PM and 7 PM, with weekday tours available if you arrange in advance. It is a good idea to contact ahead if you plan to visit on a weekday, since tours are limited to small groups.

A short gallery let the Rivarolo–Castellamonte railway, opened in 1887 and closed in 1986, pass beneath the castle and its park. Since 2018 the public park has been named after Dante Meaglia (1923–2007), a Rivarolo partisan awarded the silver medal for military valour; the children's area keeps the name Antico Gallo from the town coat of arms.
