Well worth a visit is ‘Il Castello’, once the seat of the Balbiani counts, former feudal lords of Chiavenna. The historic Palazzo Balbiani dates back pre–1477, but all that remains from the original architecture is façade and two towers after the rest was demolished during the occupation of the Grisons and reconstructed in 1930.

The church of Santa Maria di Castromuro, better known as Nossa Dona and the imposing five-story square tower. The tower, dating back to 1300, is what remains of the feudal castle Castelmur. The castle, of which few remains survive, was built about a century before the tower. The inhabitants of the fortress were, for a period, the Castelmur, an influential family from the valley, who also gave it its name. In the 15th century the fortress, which also included Lan Müraia, lost its military importance and fell into disuse, quickly becoming a ruin. In the Middle Ages, the Bregaglia formed a single parish, belonging to the diocese of Chur, and Nossa Dona was the mother church of the valley. However, the church lost importance after the Reformation and then fell into ruin in the 16th century. In the years 1845-50 it was rebuilt, apart from the Romanesque bell tower, on the old foundations by Giovanni Castelmur, the baron of Coltura. The tomb of Baron Castelmur and his wife are located in the crypt of the church. The suggestive church is touched by the route of the Valchiavenna Gravel Escape, a cycle tourism open to all that takes place the second weekend of May in Chiavenna.
