Torre Franca Castle, Medieval castle in Mattarello, Italy.

Torre Franca Castle, also known as Mattarello Castle, has a quadrangular plan with four cylindrical towers at the corners, rebuilt in the 16th century by Nicolò Trautmannsdorff. At its center stands a tall square keep, the oldest part of the complex. Remnants of a wall with Guelph battlements run along the perimeter of the surrounding land, now planted with vines.

Construction began in the 12th century under the Castelbarco family to control the road connecting Valle dell'Adige to Valsugana. The structure served as an important defensive point across medieval centuries in this mountainous region.

The village of Mattarello takes its emblem from the castle's central keep, which appears on local signs and crests. The surrounding land is now planted with vines, and sections of a wall with Guelph battlements still run along its edge.

The castle sits on private property and is not open to the public. Visitors can view the exterior from the street and study its architectural features from outside.

During World War I, the castle functioned as an Austro-Hungarian military hospital, marked by a red cross painted above the northwest entrance. This detail reminds visitors of its medical role during the conflict.
