Mù Castle, Medieval castle in Edolo, Italy.

Mù Castle is a ruined fortification on the hill east of Mù, a hamlet of Edolo in the upper Val Camonica. Its surviving walls trace a trapezoidal plan and stand up to four metres high.

In the 13th century the stronghold belonged to the bishop of Brescia, and the inhabitants of Edolo, Mù and Sonico had to guard it at night. On 29 April 1342 the Federici family began to live in the castle, as a parchment of that year recording a Girardi de Federicis de Erbanno, habitantis Roche de Mu, attests. In 1432 the Venetian Republic had the Federici castle dismantled.

The name Mù is shared by the hamlet of Edolo below the hill. In the 13th century the bishop of Brescia held the rocca, and the inhabitants of Edolo, Mù and Sonico had to keep watch over the fortification at night. A church dedicated to San Michele stood inside the walls until its demolition in 1655.

You can reach the site through marked pathways, with information available at the local tourism office in Edolo. The terrain is hilly, so wearing proper footwear is advisable for comfortable exploration.

The castle's plan is trapezoidal, not octagonal, with stretches of wall still standing up to four metres high. Inside once stood a church dedicated to Saint Michael, demolished in 1655; no trace of it appears among the ruins today.
