Foundation and the Connection to Ancient Tharros
The history of Oristano is inextricably linked to the decline of the ancient port city of Tharros. The actual birth of Oristano as a significant center is considered to be 1070. During this period, due to frequent raids by Saracen pirates and the spread of malaria along the coast, the population and authorities of Tharros were forced to seek a safer location further inland.
The decisive moment was the transfer of the Archbishop's residence and the court of the Judge (ruler) Orzocco I to this location, marking the beginning of a new era for the territory.
Key Factors of Development
The transformation of a modest settlement into a flourishing city and a powerful fortress was driven by a combination of strategic advantages:
- Geographical Protection: The city was founded amidst vast lagoons and marshes, which served as a natural barrier against sudden attacks from the sea while remaining close enough to trade routes.
- Political Status: Oristano became the capital of the Judicate of Arborea — one of the four independent states of medieval Sardinia. This attracted the administrative elite, military garrisons, and merchants to the city.
- Resources of the Tirso River: Its proximity to the mouth of Sardinia's main river provided the city with fresh water and the ability to transport goods from the island's interior.
Early Cultural and Economic Features
The economy of early Oristano was based on the rich resources of the Campidano plain. Agriculture, lagoon fishing, and crafts actively developed here. The city gained particular fame for its pottery — the production of ceramics, traditions of which are still maintained by local artisans today.
The city's cultural peak occurred during the reign of the famous Eleonora d'Arborea. It was here that the "Carta de Logu" was finalized and enacted — a progressive code of laws in the Sardinian language that regulated life on the island for several centuries and became a symbol of the region's independence and high legal culture.
