Manica Lunga is a longitudinal architectural structure built in the first half of the 1600s by Amedeo and Carlo di Castellamonte and commissioned by Carlo Emanuele I. At the time connected with the central body of the Castello Building, Manica Lunga was intended to house the ducal art gallery.
When the City of Rivoli purchased the Castello, it became a barracks. During the Second World War, it was used to welcome refugees. Such use changed its structure and new rooms were also built.
The restoration began in 1986 and ended in 2000 with the inauguration of the exhibition hall on the third floor. The architect Andrea Bruno creates the stairs and the lift using transparent materials to make the inner structure visible from the outside. The metal roof, built from scratch, is characterized by the repetition of the ribs with a central cap that runs along the entire building, greatly improving its lighting.
Manica Lunga hosts nowadays an exhibition space dedicated to temporary exhibitions, the Library and the CRRI – Castello di Rivoli Research Center, the Conference Room and the Museum Café.
