Moncalieri Castle, also known as the Royal Castle of Moncalieri, is a former royal residence located in the town of Moncalieri, near Turin in northern Italy. The castle was built in the 12th century as a defensive structure, and over the centuries it was expanded and renovated by various owners.

In the 17th century, the castle became the summer residence of the House of Savoy, the ruling family of the Kingdom of Sardinia. It was during this time that the castle underwent its most significant renovations and additions, including the construction of the central hall and the grand staircase.

The castle was used as a royal residence until the end of the monarchy in 1946. Today, it is open to the public as a museum and cultural center, with exhibits on the history of the House of Savoy and the town of Moncalieri.

One of the highlights of the castle is the magnificent Hall of Mirrors, which features a ceiling fresco by the artist Pietro Ivaldi. Other notable features include the royal apartments, the armory, and the chapel, which contains a number of religious artifacts and works of art.

The castle and its extensive gardens are a popular tourist attraction, and they are also used for cultural events and concerts. The castle is easily accessible from Turin by public transportation, and guided tours are available for visitors.
