In 1931 the Municipalities of Rome provided the spaces and on 18th September 1932 the inauguration took place at the same time of that of the monument to the Bersagliere on the square in front. Passing under the great arch of the external Door of the Vespignani, you enter the inner courtyard of the Museum where you can see the bronze busts of the most illustrious representatives of the Corps as well as the monument to Enrico Toti, the Roman volunteer Bersagliere.
From the north side of the courtyard you enter the internal spaces where there are relics and memories of the Institution and of the Corps, following the logical thread of the events that units of Bersaglieri participated in. On the ground floor there are: the room "La Marmora", the Hall of Honour and the Memorial Monument.
Inside the room "La Marmora", under the Founder's bust, you can see two carbines with powder flask for automatic measurement for a quick loading that he created in 1836; one of the two models was adopted in 1839 as basic weaponry for the first Bersaglieri units. In the Hall of Honour, along with the precious relics, there is the original Proposition: it is a document written by La Marmora to obtain from the King Carlo Alberto the foundation of the Corps and it is the bases of the consequent glorious event. The ground floor ends with the Memorial Monument dedicated to over a hundred thousand soldiers fallen for the Country; in the middle of the Room there is the saber that La Marmora held on 8th April 1848 in Goito, while on the wall in front there is an oil portrait of the Founder placed side by side with two display cases containing the medals to the collective valour awarded to the Bersaglieri Units from 1848 to present.
On the first floor you can see relics, documents and memories of the Risorgimento campaigns, from 1848 to 1866, with historical and documentary interest such as uniforms, weapons, personal melee weapons and memories of the campaigns against the brigandage in the southern provinces after 1860.
The second floor of the southern side of the building has got three big rooms dedicated to the colonial campaigns: the first disembarkation of the Bersaglieri in Massaua on 5th February 1885, the battles of Agordat (1890 and 1893) and Cassala (1894), the battle of Adua (1896), the expedition in China (1900), the operations for the conquest of Libya and Dodecanneso (1911-1913), the conquest of Eastern Africa (1935-1936).
The lower floor, first floor of the southern side, is dedicated to the First World War (1915-1918): plaques, photographs, unit pennants, commemorative statues, portrait and medal collections of Commanders and Bersaglieri, Italian and Austrian weapons such as the machine gun that, at 4.00 p.m. of 4th November 1918 in Paradiso, mowed down the nineteen-year-old first lieutenant Alberto Riva of Villasanta and his Bersaglieri (the last Fallen soldiers of the war).
The ground floor of the southern side is dedicated to the World War II (1940-1945). It exhibits relics and objects from the different theatres of operations where the Bersaglieri fought with great valour and sacrifice both in good times and in misfortune.
Along with the exhibition rooms, the Museum has got a library and a historical archive; they house volumes, rare booklets, original documents of those who served in the Corps that testify the spirit, the training and the employment methods of the first units.
Porta Pia is one of the access roads carved on the ancient Aurelian walls, the urban walls of the classical period. They are a masterpiece of the military architecture, started by the Emperor Aureliano in 271 and remained in efficiency thanks to the care of the Popes for sixteen centuries. Walking along the walls towards Corso d'Italia, you arrive to Porta Pinciana and from there to Villa Borghese.
