The Dolomites are not one range on the World Heritage list: they are 9 separate mountain systems, inscribed together on June 26, 2009, spread across 5 provinces and totaling around 142,0002 hectares.
Nine systems, inscribed as one property
The Dolomites entered the World Heritage list on June 26, 2009 at the Seville session, as a serial natural property made of 9 systems, distributed between Veneto in the province of Belluno, Friuli-Venezia Giulia in the provinces of Pordenone and Udine, the autonomous province of Bolzano and the autonomous province of Trento.
Serial means the property is a set of discontinuous areas that share an argument, not a single boundary drawn around a region. Between one listed system and the next there is unlisted land with roads, villages and ski lifts on it.
That is the single most useful thing to know before planning a trip. Asking whether you will be in the Dolomites UNESCO site is a different question from asking whether you will be in the Dolomites.
The list, system by system
The 9 systems are Pelmo and Croda da Lago, the Marmolada, Pale di San Martino with San Lucano, Dolomiti Bellunesi and Vette Feltrine, the Dolomiti Friulane and d'Oltre Piave, the Northern Dolomites, Puez-Odle, Sciliar-Catinaccio with Latemar, the Brenta Dolomites and the Bletterbach.
Together they cover around 142,0002 hectares across the 5 provinces of Bolzano, Trento, Belluno, Pordenone and Udine. The Bletterbach is the outlier of the group: a gorge rather than a peak, listed for the rock sequence exposed in its walls.
The naming varies slightly between official sources, and the provincial allocation of individual systems needs refining against the nomination file before anyone treats the list above as closed. The number, 9, does not vary.
Veneto holds five of the nine
5 of the 9 systems fall in Veneto, all of them in the province of Belluno: Pelmo-Croda da Lago, the Marmolada, two portions of Pale-Dolomiti Bellunesi, and the Dolomiti Friulane.
That is why Veneto carries the largest share of the property, a fact that surprises people who associate the Dolomites with Alto Adige and its German speaking valleys. The best known photographs are often taken from the Belluno side of a boundary.
Nomenclature differs here too: what Veneto calls Pale-Dolomiti Bellunesi appears elsewhere as Pale di San Martino and Dolomiti Bellunesi. Same rock, different administrative habit.
Trentino, Alto Adige and Friuli
4 of the 9 systems fall in Trentino: the Marmolada, Pale di San Martino with the Vette Feltrine, Catinaccio and Latemar, and the Brenta Dolomites, the group that sits apart from the rest of the chain.
In Alto Adige the listed systems include Puez-Odle, Sciliar-Catinaccio and Latemar, the Northern Dolomites and the Bletterbach. In Friuli-Venezia Giulia there is one, the Dolomiti Friulane and d'Oltre Piave, spanning the provinces of Pordenone and Udine.
Systems straddle borders, which is why the same name appears under two administrations. The Marmolada is counted by both Veneto and Trentino, and that is not an error in either list.
One property, one foundation, four administrations
Management is in the hands of the Fondazione Dolomiti UNESCO, constituted on May 13, 2010 by the provinces and regions involved, less than a year after the inscription.
A single foundation over 4 administrations is the practical answer to a serial property that crosses three regions and two autonomous provinces with different languages, different tourist boards and different planning law.
One figure is missing from this page on purpose: the total listed surface is not declared on the official pages we could open, and the whc.unesco.org site refuses automated reading, so the around 142,0002 hectares above comes from Italian institutional sources rather than from the nomination itself. See Veneto, the province of Bolzano and mountains in Italy.
