Montecitorio is not the only building in which the bodies and offices of the Chamber of Deputies are located. Some parliamentary Groups are based in “Palazzo dei Gruppi” (Building of the Parliamentary Groups), while the ancient complex of “Santa Maria sopra Minerva” is home to Bicameral Committees, to the Historical Archives and the Library of the Chamber of Deputies. The “Santa Maria in Campo Marzio” complex on Vicolo Valdina, a group of buildings whose origins date back to the days of early Christianity, hosts exhibitions and conferences. “Palazzo Theodoli-Bianchelli” and “Palazzo ex Banco di Napoli” contain several offices, while the “Palazzi Marini” complex is mainly given over to MPs’ offices.
