In Italy the unit institutionally intended to act as an honour guard to the President of the Italian Republic is the Corazzieri Regiment, a special branch of the Carabinieri. The Corazzieri follow the President during official occasions and are also partly responsible for the internal security of the Quirinal Palace. In addition to the Corazzieri, there are other honour units chosen from the different Armed Forces, specifically for representation purposes. These units have to stand guard at important places, such as the gates of the seats of the Chamber of Deputies and the Senate, at the Tomb of the Unknown Soldier in the Altar of the Homeland, and at the gates of the Quirinal Palace.
