The Dolomites, UNESCO World Heritage

On 26 June 2009 the Dolomites were inscribed on the UNESCO World Heritage List for their monumental beauty (criterion VII) and their outstanding geological and geomorphological significance (criterion VIII), recognised as “among the most beautiful mountain landscapes in the world”. They are one of only four natural UNESCO sites in the entire Alpine arc.

Born from the sea: the "Pale Mountains"

Around 250 million years ago the Dolomites were a collection of shells, corals and algae submerged in a tropical sea. They emerged roughly 70 million years ago and were then carved by time and the elements: today they reveal, in a superbly exposed geology, a cross-section of marine life from the Triassic period. It is this extraordinary worldwide concentration of carbonate formations that makes the Dolomites a treasure for Earth Sciences.

The pale colour of the dolomite rock gives them the name “Pale Mountains”. At dawn and especially at sunset the rock blazes pink and fiery red: this is the enrosadira, the phenomenon that inspired legends such as that of King Laurin and his rose garden, linked to the Catinaccio massif.

The discovery of the Dolomites

Their story in the eyes of the world begins at the end of the eighteenth century. In 1789 the French naturalist Déodat de Dolomieu identified the distinctive mineral that makes them up, soon afterwards named “dolomite” in his honour by Nicolas de Saussure. In 1822 Leopold von Buch studied their stratigraphy, drawing the attention of his friend Alexander von Humboldt. It was the travel book The Dolomite Mountains by Gilbert and Churchill (1864), however, that introduced these mountains to the general public, extending the name from the mineral to the entire region.

The 9 Dolomites UNESCO systems

The site consists of nine non-contiguous mountain systems, considered as a single unified whole, covering a total area of more than 231,000 hectares across five provinces (Belluno, Bolzano, Trento, Pordenone, Udine) and three regions (Veneto, Trentino-Alto Adige, Friuli Venezia Giulia).

Who protects the Dolomites UNESCO site

Management of the site is entrusted to the Fondazione Dolomiti UNESCO, which brings together the provinces of Belluno, Bolzano-Alto Adige, Trento, Pordenone and Udine together with the Veneto and Friuli Venezia Giulia regions. The aim is to reconcile environmental protection with sustainable development and responsible tourism, passing this heritage on to future generations.

Frequently asked questions about the Dolomites UNESCO

When were the Dolomites inscribed as a UNESCO World Heritage Site?

The Dolomites were inscribed on the World Heritage List on 26 June 2009, under natural criteria VII (exceptional beauty) and VIII (geological significance), and recognised as "among the most beautiful mountain landscapes in the world".

How many systems make up the Dolomites UNESCO site?

The property consists of 9 non-contiguous mountain systems considered as a single unified whole, covering a total area of more than 231,000 hectares across five provinces and three regions.

Why are they called the Dolomites?

The name comes from the French naturalist Déodat de Dolomieu, who in 1789 studied the distinctive rock that makes up these mountains, later named "dolomite" in his honour. Because of their pale colour they are also known as the "Pale Mountains" (Monti Pallidi).

What is the enrosadira?

It is the phenomenon by which the dolomite rock turns from pink to fiery red at dawn and especially at sunset. The colour shifts depend on the position of the sun and is particularly vivid on summer evenings.
