Tourist information

Capital of the Aosta Valley, Aosta is located at 583 meters above sea level, in a valley surrounded by magnificent mountains near the confluence of the Buthier and Doria rivers, at the point of convergence of the roads that descend from the Grande and Piccolo San Bernardo.

Founded by the Romans around 25 BC, with the name of Augusta Praetoria, at the beginning of the Augustan era it was a garrison created with the aim of defending the paths that led to the countries beyond the Alps.


The Roman footprint is still clearly visible in the urban structure, in the monuments of the city and in the imposing defensive walls, adapted and subsequently transformed during the medieval era.

Going along the perimeter of the walls starting from the Porta Praetoria, which constituted the main access to the Roman city, you will find the Tour Fromage, dating back to the Middle Ages, the Torre dei Balivi, also from the Middle Ages and built on the structures of the pre-existing Roman tower, the Torre del Lebbroso, transformed into a feudal residence by the noble Friour, the Torre di Bramafam and the Torre Pailleron, to return again to the Porta Praetoria.

The Arch of Augustus is considered the symbol of the city of Aosta, built in 25 BC on the occasion of the foundation of the city and following the victory of the Romans over the Salassi, who were the people who had inhabited this territory until then.


The arch is located near the remains of the Roman bridge, along the road leading to Porta Praetoria.

Under the vault of the arch there is a copy of a fifteenth-century wooden Crucifix, which had been placed there as a votive offer against the frequent flooding of the nearby Buthier stream, the original Crucifix is ​​kept in the Treasure Museum included in the complex of the Cathedral of Aosta.

After passing Porta Praetoria, flanked by the twelfth-century Tour de la Trinité, a street leads to the Archaeological Park of the Roman Theater, where you can admire the ruins of the prestigious monument, of which a part of the high wall of the facade remains, having more orders of windows, in addition to the lower part of the auditorium and the scene.


What see

The building preserves one of the main testimonies of the pictorial and figurative culture of the years around the year 1000, called the Ottonian because it flourished during the reigns of the emperors of the house of Saxony, when the progenitor Otto I reigned from which it derived its name.

Another example of the Ottonian style is present in Aosta in the monumental complex of the Collegiata di Sant’Orso, composed of the Collegiate, dedicated to Saints Peter and Bear, dating back to the fifth century but rebuilt around the eleventh century.

The museum is housed in a building located in the place where the Porta Principalis Sinistra was located in Roman times, the remains of the door are visible in the basement.
