Caldonazzo (German: Gallnötsch, Cimbrian: Kalnètsch[3]) is a commune in Valsugana, in Trentino, northern Italy.

Traces from the time of the Migration Period indicate that the town played a significant role in history on multiple occasions.

The border with the Kingdom of Italy was only a few kilometers away on the Folgaria plateau, where numerous bunkers and structures from that era can still be seen today.

Although weathered, the old masonry still clearly displays a fresco of a coat of arms that Austrians will find familiar, as it features the well-known red-white-red shield.

Inside, an old painting depicting Pope Sixtus surrounded by Saints Borromeo, Francis, and Sebastian serves as a reminder of the plague that ravaged Caldonazzo in 1630.
