Characteristics
Entities	France; Italy
Length	515 km (320 mi)

The France–Italy border is 515 km (320 mi) long. It runs from the Alps in the north, a region in which it passes over Mont Blanc, down to the Mediterranean coast in the south. Three national parks are located along the border: Vanoise National Park and Mercantour National Park on the French side and Gran Paradiso National Park on the Italian side.

Features

The France–Italy border is mainly mountainous. It is 515 kilometres (320 mi) long,^[1] in southeast France and northwest Italy. It begins at the west tripoint of France–Italy–Switzerland (45°55′23″N 07°02′40″E / 45.92306°N 7.04444°E / 45.92306; 7.04444) near the top of Mont Dolent (3,820 m), in the French commune of Chamonix (department of Haute-Savoie), the Italian city of Courmayeur (Aosta Valley) and the Swiss commune of Orsières (canton of Valais).

The boundary then follows a general direction towards south, to the Mediterranean, it reaches the sea at Menton in France and Ventimiglia in Italy. The border separates three regions (Aosta Valley, Piedmont and Liguria) and four provinces of Italy (Aosta, Turin, Cuneo and Imperia) from two regions (Auvergne-Rhône-Alpes and Provence-Alpes-Côte d'Azur) and five departments of France (Haute-Savoie, Savoie, Hautes-Alpes, Alpes-de-Haute-Provence and Alpes-Maritimes).

The border between the two countries dates back to that separating the Kingdom of Sardinia and France during the 19th century. In 1860, the Treaty of Turin links the Savoy and County of Nice to France; the border between the French Empire and the Kingdom of Sardinia was surveyed the following year.

At the conclusion of the Battle of France in World War II, Italy claimed and administered French territory under the terms of the armistice of 24 June 1940 (the Franco-Italian armistice signed at the Incisa villa near Rome) which were extended from 11 November 1942. The Germans occupied the Italian zone from 1943, and the territory was finally liberated by France in 1944. The border was then changed by the Treaty of Paris in 1947, when France acquired Tende, La Brigue, Mont Chaberton and the Lake of Mont Cenis.

In the 21st century, an ongoing issue to be resolved concerns the demarcation of the border at the top of Mont Blanc.^[3]
