Ville d'Anaunia was formed in 2016 from the merger of the three formerly independent municipalities of Nanno, Tassullo and Tuenno. The municipal area, with its main seat of Tuenno, extends at an average altitude of 629 m a.s.l. and has 4,764 inhabitants. The associated hamlets are Campo, Nanno, Pavillo, Portolo, Rallo, Sanzenone, Tassullo and Tuenno.

From the orographic right side of the Val di Non valley, south of the main village of Cles, Ville d'Anaunia extends to the Val di Tovel valley with its famous lake and into the majestic Adamello-Brenta Nature Park. The villages can look back on a long tradition of farming. The area was already settled in prehistoric times, and later the individual villages were united for centuries under the parish of Tassullo (Pieve di Tassullo).

Today, however, apple-growing dominates here. Due to the scenic beauty with its natural spectacles and the rich cultural offer of churches and castles, the area of Ville d'Anaunia is also very popular with guests.
