The castle was constructed using stones taken from the nearby ruins of the Roman city of Venusia, including parts of the amphitheater.
Pirro del Balzo built the fortress on top of existing foundations belonging to a previous Norman castle.
The four corner towers are physically connected by curtains of thick masonry designed to withstand siege artillery of the period.
The National Archaeological Museum within the castle houses findings from the Paleolithic site of Notarchirico, one of the oldest human occupation sites in Europe.
The Aragonese Castle in Venosa is a 15th-century fortress featuring a square floor plan with four cylindrical corner towers and a surrounding moat. Commissioned by Pirro del Balzo in 1470, the structure incorporates materials salvaged from the nearby Roman archaeological site of Venusia. The castle serves as the municipal seat and houses the National Archaeological Museum of Venosa. Visitors can explore the internal courtyard, which displays a collection of Roman inscriptions and architectural fragments. The structure replaced an earlier Norman castle, utilizing its foundations to maintain a strategic defensive position. It stands as a prime example of transition-era military architecture in the Basilicata region. The museum collections inside focus on the pre-Roman and Roman history of the Venosa valley.
The internal courtyard from the ground level provides a balanced view of the four defensive towers and the stone masonry.
Visit the National Archaeological Museum located within the castle walls to understand the context of the artifacts on display.
Walk the perimeter of the moat to appreciate the scale of the fortification walls.
Combine your visit with a trip to the nearby Abbey of the Santissima Trinità.
Do not attempt to climb the exterior tower walls, as they are structurally preserved for historical integrity rather than recreational use.
Closed on Mondays.
