The district community of Pustertal, established in 1969, incorporates the communities of eastern South Tyrol and, from an area point of view, is the biggest district community in the province. The province is named after its main valley that is drained by the Rienz, whose extension forms the Drautal which is an important transport connection to East Tyrol. The administrative seat of the community is located at Bruneck. The town is one of the most important industrial areas in South Tyrol with a rapidly increasing population. Here the Gadertal, one of the last Ladin-speaking regions, runs into the main valley. The Tauferer Tal opens up to the north with its main town of Sand in Taufers and in its continuation makes up the Ahrntal. Further important towns along the Rienz are Olang at the entrance to the Antholzer Tal, Toblach and Innichen, the location of the oldest religious institution in the Tyrol. The numerous mountains and lakes are also characteristic of the Pustertal.
