Geography

The Aosta Valley is an Alpine valley which, with its tributary valleys, includes the Italian slopes of Mont Blanc, Monte Rosa, Gran Paradiso and the Matterhorn; its highest peak is Mont Blanc (). This makes it the highest region in Italy, based on the highest point in each region.

Climate

The valleys, usually above , annually have a cold continental climate (Dfc). In this climate, the snow season is very long, lasting as long as 8 to 9 months at the highest points. During the summer, mist occurs almost every day. These areas are the wettest in the western Alps. Temperatures in January are low, between , and in July are between .

Areas between usually have a tundra climate (ET), where every month has an average temperature below . This climate may be either a kind of more severe cold oceanic climate, with a low summer average but mild winters, sometimes above , especially near lakes, or a more severe cold continental climate, with a very low winter average. Temperature averages in Plateau Rosa, at high, are in January and in July. It is the coldest place in Italy where the climate is verifiable.

In the past, above , all months had an average temperature below freezing, with a perpetual frost climate (EF). In recent years, however, there has been a rise in temperatures. See, as an example, the data for Plateau Rosa.

In 1031–1032, Humbert I of Savoy, the founder of the House of Savoy, received the title Count of Aosta from Emperor Conrad II of the Franconian line and built himself a commanding fortification at Bard. Saint Anselm of Canterbury was born in Aosta in 1033 or 1034. The region was divided among strongly fortified castles, and in 1191, Thomas I of Savoy found it necessary to grant to the communes a Charte des franchises ("Charter of Liberties") which preserved autonomy—rights that were fiercely defended until 1770, when they were revoked to tie Aosta more closely to Piedmont, but which were again demanded during post-Napoleonic times. In the mid-13th century, Emperor Frederick II made the County of Aosta a duchy (see Duke of Aosta), and its arms charged with a lion rampant were carried in the Savoy arms until the reunification of Italy in 1870.

The region remained part of Savoy lands, with the exceptions of French occupations from 1539 to 1563, later in 1691, and then between 1704 and 1706. It was also ruled by the First French Empire between 1800 and 1814. During French rule, it was part of Aoste arrondissement in Doire department. As part of the Kingdom of Sardinia, it joined the new Kingdom of Italy in 1861.

French forces briefly controlled the area at the end of World War II, but withdrew under British and American pressure. The region gained special autonomous status after the end of World War II; the province of Aosta ceased to exist in 1945. The latest regional election was held in late September 2025. The current President is Renzo Testolin, first elected in 2023 supported by a coalition of autonomist and progressive lists.

The economy of the Aosta Valley is based above all on the tertiary sector, in particular on tourism. Due to the autonomy conferred by the special statute, the public sector, which administers most of the regional financial resources, plays a role of primary importance in the Aosta Valley economy. The industries are concentrated in the lower valley (between Verrès-Champdepraz and Pont-Saint-Martin) and are often small to medium sized. However, the contribution of agriculture and livestock to the regional economy is modest. Potatoes, apples, vines, barley are grown and cattle are raised. The artisanal production is significant, in which wooden sculpture emerges.

Aosta Valley has many small and picturesque villages, three of them have been selected by (), a non-profit private association of small Italian towns of strong historical and artistic interest, that was founded on the initiative of the Tourism Council of the National Association of Italian Municipalities. These villages are:

Bard
Fontainemore
Etroubles

Notable wines include two white wines from Morgex (Blanc de Morgex et de La Salle and Chaudelune), a red wine blend from Arvier (Enfer d'Arvier) and one from Gamay. The Valle d'Aosta DOC (or Vallée d'Aoste DOC, in French) is an Italian denominazione di origine controllata located in the Aosta Valley of north-west Italy. Surrounded by the Alps, the Valle d'Aosta is home to the highest elevated vineyards in all of Europe. The principal winemaking region of the Valle d'Aosta is found along the eastern banks of the Dora Baltea (fr., Doire baltée) river with the city of Aosta serving as the central winemaking location. The region is divided into three main vineyard areas; the upper valley, Valdigne, the central valley (locally Valle centrale in Italian, Vallée centrale in French) and the lower valley, (locally Bassa valle in Italian, Basse vallée in French).
