Arch of Augustus in Susa

Highlight • Monument

Susa is a city rich in history and monuments. Of Roman origin (the ancient Segusium), it preserves, stratified in the urban fabric of the historic center, evidence of the Roman era (of which the Arch of Augustus and the Roman arena are the most striking examples!), notable medieval remains (castle of the Marchioness Adelaide, historic village, Porta Savoia...).
A visit route can start from the station square (convenient for parking), then continuing along Via Roma (full of shops and bars), crossing the bridge over the Dora, then continuing along the main street until turning right into Via Palazzo di Città (thus passing under the thirteenth-century Civic Tower).
Here the medieval porticoes are notable, continuing straight you arrive at the foot of the imposing castle of the Marchioness Adelaide, here you will find the signs for the Roman arena (detour to the left). Back, continue climbing the steps at the foot of the castle to the top where, in a small space, remains of distant eras coexist: the Roman aqueduct, at the foot cup-shaped rocks perhaps from the Celtic era, not far away the Arch of Augustus and the entrance to the internal courtyard of the castle. Going down, you pass under the Arch of Augustus, cross the public gardens admiring the remains of the medieval walls and arrive in Piazza Savoia. Here you turn right, pass under the beautiful Porta Savoia and arrive in the most suggestive corner of Susa, Piazza S. Giusto, dominated by the beautiful cathedral of the same name.
You can admire some well-renovated medieval houses before taking Via Francesco Rolando which quickly leads back to Via Roma.

Mont Cenis Pass

Highlight • Mountain Pass

The Mont Cenis hill connects the Susa valley, Italy, with the Maurienne, France. The pass, located at an altitude of 2,085 metres, is located entirely on French soil.
Near Mont Cenis there is a pyramid that houses a museum, where it is possible to appreciate the history of this famous Alpine pass.

Lanslebourg

Highlight • Other

This cute little place really offers a little bit of everything. Despite its focus on tourism and mountain sports, Lanslebourg has retained the typical charm of a French mountain village. Although the village is relatively small with just over 600 inhabitants, there is everything your heart desires, from hotels to good restaurants and sensational views.

Barrière de L'Esseillon

Highlight • Historical Site

Fort-Victor Emmanuel, better known as the Barrière de L'Esseillon, is a series of five forts built in the 19th century on the rocky lock or "rocky close" which closes the upper valley of the Arc like a padlock. These forts served to protect the kingdom of Piedmont-Sardinia from a possible French invasion. Borders change but buildings remain. Each of the forts bears the name of a member of the Savoy family, the most famous being that of Victor Emmanuel.

Be careful not to confuse it with the innumerable Forts Vauban which dot the borders of the current French territory.
