Diego Sandoval of Castro Castle — Nova Siri Castle
The Castle of Nova Siri — also known as the Diego Sandoval of Castro Castle after its fifteenth-century Aragonese lord — is a medieval fortification perched on a hill above the Ionian coast in the province of Matera, Basilicata. Built to defend the ancient hilltop settlement near the site of the Greek colony of Siris, the castle commands panoramic views across the Gulf of Taranto and the surrounding Lucanian countryside. It stands as one of the principal heritage landmarks of the Nova Siri comune and a rare surviving example of Aragonese military architecture in this stretch of the southern Tyrrhenian and Ionian frontier.

Overview
Nova Siri is a town in the province of Matera set on a hill at approximately 350 metres above sea level, some nine kilometres from the Ionian coast. The castle dominates the historic centre of the old town and is closely associated with Diego Sandoval of Castro, a Spanish nobleman who held the fief under the Crown of Aragon during the fifteenth century. The structure reflects the military and administrative reach of Aragonese power in southern Italy, a period that reshaped the castles, churches, and urban fabric of Basilicata and Calabria.
The site also carries layers of much older history: Nova Siri lies near Siris, one of the earliest Greek colonies on the Ionian coast of Magna Graecia, founded around the seventh century BC. The hilltop position chosen for the medieval castle almost certainly echoes earlier defensive use of the same ridge.
Today the castle and its surroundings form the historic core of Nova Siri Centro, distinguishable from the modern coastal town of Nova Siri Scalo that developed from the 1970s onwards.
History
The fortification’s origins are medieval, linked to the Norman and Angevin organisation of the Terra d’Otranto and Basilicata frontier zone. The castle took on its current character and acquired its territorial name under Diego Sandoval of Castro, who held Nova Siri as a feudal possession during the period of Aragonese rule over the Kingdom of Naples (1442–1503).
The Aragonese phase was one of intense castle-building and reinforcement across southern Italy, as the Crown of Aragon consolidated control against French Angevin rivals and Ottoman naval incursions along the Ionian coast. Coastal and hilltop castles like Nova Siri were integrated into a chain of signal and defence points stretching from Puglia into Calabria.
After the Spanish viceroyalty absorbed the Kingdom of Naples in the sixteenth century, feudal holdings changed hands multiple times. The castle declined as an active military post but survived as a landmark in the rural Lucanian landscape.
What you see
The castle presents the typical silhouette of a southern Italian hilltop fortification: compact towers, thick rubble-masonry curtain walls, and a commanding position that makes maximum use of the natural topography. The stonework shows layers of construction from different periods, with medieval core fabric overlaid by Aragonese reinforcements.
From the castle perimeter, the view extends across the Ionian Sea and the coastal plain, with the Gulf of Taranto visible on clear days. The surrounding old town retains narrow lanes and stone-built houses characteristic of Lucanian hill settlements.
The virtual-tour element associated with this listing (360° documentation) reflects ongoing efforts to make the monument accessible to a wider audience beyond on-site visits.
Cultural significance
Nova Siri Castle is a tangible reminder of the complex feudal and dynastic history of Basilicata under successive Norman, Angevin, Aragonese, and Spanish regimes — a layering of power that shaped the physical landscape of the region’s hill towns far more profoundly than the ancient Greek and Roman periods that preceded it. The association with Diego Sandoval of Castro connects the site to the broader Spanish-Italian cultural exchange of the fifteenth and sixteenth centuries.
Proximity to the ancient site of Siris adds archaeological depth: the entire Nova Siri hill represents a palimpsest of occupation from Magna Graecia to the modern era, making it of interest to historians of both classical antiquity and medieval southern Italy.

Getting there
Nova Siri is served by a railway station (Nova Siri Scalo) on the Ionian coastal line connecting Taranto and Reggio Calabria, though services are infrequent. By car, the SS106 Jonica coastal road provides the most practical approach; the old town and castle are reached by the hill road from the coastal settlement. The nearest significant cities are Matera (approximately 65 km north-west) and Taranto (approximately 60 km north-east). A car is strongly recommended for visiting the area.
