The Venosa Castle is a historic fortified building located in the homonymous town in the province of Potenza. Commonly referred to as the Aragonese Castle because it was built by Duke Pirro del Balzo during the Aragonese dynasty period, it is situated at the southern end of the plateau occupied by the urban area of the city.
Its construction dates back to 1470, commissioned by Duke Pirro del Balzo as part of a broader fortification project. It is an imposing structure, with a square plan featuring four cylindrical towers. The Del Balzo coat of arms, a radiant sun, is visible on the western tower. The construction of the castle and the excavation of the moat, in accordance with the new principles of fortification, led to the demolition of the Romanesque cathedral and the surrounding district. Therefore, a new cathedral was built in an expansion of the settlement on the lower part of the plateau where the city stands.
It was transformed from a fortress into a noble residence by Carlo and Emanuele Gesualdo, with the addition of the inner loggia, the northwest wing, and the outworks at the base of the towers. From 1612, it hosted the Academy of the Renaissance.
The four cylindrical towers at the corners, initially crowned with battlements and probably conical roofs, are supported by outworks that constitute the scarp of the moat, used as prisons. The entire building, accessed via a drawbridge, is surrounded by a deep moat. Inside, there is a large courtyard surrounded by a Renaissance loggia. In front of the castle, there is a porticoed square and a monumental fountain granted to Venosa by Charles I of Anjou.
Within its walls, in the rooms located in the basements of the towers, the castle houses the National Museum of Venosa, which primarily preserves the rich evidence of the Roman colony of Venusia.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
