Trentino: four of the nine UNESCO Dolomite systems

Four of the nine mountain systems that make up the UNESCO Dolomites, inscribed in 2009, fall in Trentino: the Marmolada, the Pale di San Martino with the Vette Feltrine, Catinaccio and Latemar, and the Brenta Dolomites.

The four systems, and the one that stands apart

Trentino holds 4 of the 9 Dolomite systems on the World Heritage list. The management body, the Fondazione Dolomiti UNESCO, dates from May 13, 2010.

Of the four, the Brenta is the odd one. The official description calls it the only Dolomite group separated from the rest of the chain, and on a map it does stand apart from the other three.

Catinaccio and Latemar are shared with Alto Adige: the same system turns up on the Bolzano list, because it crosses the border between the two provinces.

Marmolada: the summit of the list

The Marmolada system includes Punta Penia, 3,343⁴ meters, the highest summit anywhere in the Dolomites. Its glacier is the largest in the Dolomites and it is shrinking fast.

The mountain sits on a provincial border. Since a 2018 definition the line between Trento and Belluno follows the watershed along its ridge, so the listed system has a Trentino face and a Veneto face.

Two World Heritage sites for the region

Trentino-Alto Adige counts 2 World Heritage sites in 2026: the Dolomites and the prehistoric pile dwellings around the Alps, listed in 2011. Neither belongs to the region alone.

The pile dwellings are a serial site spread over five Italian regions: Friuli-Venezia Giulia, Lombardy, Piedmont, Trentino-Alto Adige and Veneto. The sources behind this page do not say which components are in Trentino, so none is named here.

The Geopark: a UNESCO label that is not World Heritage

The Adamello Brenta natural park is a UNESCO Global Geopark, a separate programme from the World Heritage list, and it does not add to the regional count of 2.

The park was established in 1967 and covers 62,051⁵ hectares, with over 80 lakes and the Adamello glacier. It also contains the Brenta Dolomites, so one stretch of mountain is both a World Heritage system and part of a Geopark.

Two labels on one ridge is not a contradiction. World Heritage protects the Dolomites as a landscape of global value; the Geopark recognises the geology of the whole park, lakes and glacier included.
