Le Malgreien, today known as Dodiciville or Zwölfmalgreien, is a cadastral community of Bolzano, which used to be independent and already had about 10,000 inhabitants in 1910.

In the historical area of Dodiciville there are 12 “Malgreien” (in fact, “Dodici” means 12 in Italian language), i.e. agricultural areas, which here in Bolzano are mainly focused on wine growing: St. Peter at the entrance to the Val Sarentino valley, St. John in Town with the church of the same name, today’s district of Rencio, the wine-growing area of Santa Maddalena, Santa Giustina on the slope of the Renon plateau, the slopes south-east of Santa Giustina (Bolzano Leitach), Campiglio on the left bank of the Isarco river, Campegno (with the Colle hill), the Virgolo hill, the districts of Oltrisarco-Aslago and the famous Piazza della Dogana square (Zollstange, in German).

The latter is located just outside the historic town centre and is the former customs office of the trading centre of Bolzano: It forms the centre of the existing Dodiciville. Today the “Löwengrube”, one of the oldest inns of the town, as well as numerous regional offices are located there. A little further on, but still in Dodiciville, are the railway station of Bolzano, the valley station of the Renon Cable Car and that of the Colle Cable Car.
