Cottian Alps in the context of "Dora Riparia"

The Po (/poʊ/ POH, Italian: [ˈpɔ]) is the longest river in Italy. It flows eastward across northern Italy, starting from the Cottian Alps. The river's length is 652 km (405 mi), or 682 km (424 mi) if the Maira, a right bank tributary, is included. The headwaters of the Po are formed by a spring seeping from a stony hillside at Pian del Re, a flat place at the head of the Val Po under the northwest face of Monviso. The Po then extends along the 45th parallel north before ending at a delta projecting into the Adriatic Sea near Venice.

Draining a basin of 74,000 km (29,000 sq mi), the Po is characterized by its large discharge (several rivers over 1,000 km have a discharge inferior or equal to the Po). It is, with the Rhône and Nile, one of the three Mediterranean rivers with the largest water discharge. As a result of its characteristics, the river is subject to heavy flooding. Consequently, over half its length is controlled with embankments.

The Susa Valley (Arpitan: Vâl Susa; Piedmontese: Valsusa; Occitan: Val d'Ors; Italian: Val di Susa; French: Val de Suse) is a valley in the Metropolitan City of Turin, Piedmont region of northern Italy, located between the Graian Alps in the north and the Cottian Alps in the south. It is one of the longest valleys of the Italian Alps. It extends over 50 kilometres (31 mi) in an east-west direction from the French border to the outskirts of Turin. The valley takes its name from the city of Susa which lies in the valley. The Dora Riparia river, a tributary of the Po, flows through the valley.

A motorway runs through the valley from Turin to Chambéry in France through the Fréjus tunnel or by crossing the Col du Mont Cenis (2083m), and to Briançon, also in France, over the Col de Montgenèvre.

The Arch of Augustus is an important monument constructed in the city of Susa, Piedmont, in the province of Turin. It was originally built at the end of the 1st century BC to record the renewed alliance between Emperor Augustus and Marcus Julius Cottius, a Celto-Ligurian ruler who had been made king and Roman prefect of the Cottian Alps. The arch, together with other remains from the period, such as the Roman amphitheatre and a Roman aqueduct, underscore the importance that the city of Susa had during the Roman period.

The Waldensians, also known as Waldenses (/wɔːlˈdɛnsiːz, wɒl-/), Vallenses, Valdesi, or Vaudois, are adherents of a church tradition that began as an ascetic movement within Western Christianity before the Reformation. Originally known as the Poor of Lyon in the late 12th century, the movement spread to the Cottian Alps in what is today France and Italy. The founding of the Waldensians is attributed to Peter Waldo, a wealthy merchant who gave away his property around 1173, preaching apostolic poverty as the way to perfection.

In some aspects the Waldensians of the Middle Ages could be seen as proto-Protestants, but they mostly did not raise the doctrinal objections characteristic of sixteenth-century Protestant leaders. They came to align themselves with Protestantism: with the Resolutions of Chanforan [fr] on 12 September 1532, they formally became a part of the Calvinist tradition. They were nearly annihilated in the seventeenth century.

The Maira is an Italian river, a right tributary of the Po, which runs through the province of Cuneo in eastern Piedmont. Its source is in the Cottian Alps near the Col de Mary (or Col Maurin) on the French border. Its name, in the Occitan and Piedmontese languages, means ‘lean’ or ‘meagre’.

During its upper course the river descends rapidly through the scenic Valle Maira, passing through the centres of Acceglio, Prazzo, Stroppo, Macra, San Damiano Macra, Cartignano and Dronero; at Busca it leaves the valley and enters the plains, continuing through Villafalletto and Vottignasco. It passes just to the left of Savigliano, while the Grana-Mellea, its main tributary, passes to the right of the town: they continue in parallel before joining near Cavallermaggiore.

The Valle Po (literally "Po valley") is a valley of the Cottian Alps in the province of Cuneo, Piedmont, Northern Italy.

Monte Viso or Monviso (Italian: [moɱˈviːzo]; Occitan: Vísol [ˈvizul]; Piedmontese: Brich ëd Viso [ˈbrik əd ˈvizʊ] or simply Viso) is the highest mountain of the Cottian Alps, located in Piedmont, Italy, close to the French border. Monte Viso is well known for its pyramid-like shape. Because it is higher than all its neighbouring peaks by about 500 m, it can be seen from a great distance, including from the Piedmontese plateau, the Langhe, the Theodulpass in the Zermatt ski area, the Col du Galibier and the summits of the Mont Blanc massif. On a very clear day, it can be seen from the spires of Milan Cathedral.

It has been suggested that Monte Viso could be one of the mountains which inspired the Paramount logo, even though the company has denied the claims. In Italy it is also known as il Re di Pietra ("the Stone King") because of its prominence within the western Italian Alps. It was declared a cross-border UNESCO biosphere reserve in 2013.The longest river of Italy, River Po, is born at the mountain's foot.
