The history of Cáceres dates back to the Roman era. The city was founded around 25 BC (according to other sources — in 34 BC) by the Roman proconsul Lucius Cornelius Balbus. Initially, the settlement was granted the status of a colony and named Norba Caesarina. A significant military camp, Castra Caecilia, was also located nearby, traces of which have survived to this day.
Several key factors contributed to the transformation of the small settlement into a significant city:
- Strategic Geography: The city was established on elevated ground, providing natural protection against raids and allowing control over the surrounding plains.
- Transport Accessibility: Cáceres was situated near the Vía de la Plata ("The Silver Way") — a vital Roman highway connecting Mérida and Astorga. This ensured a constant flow of goods and travellers.
- Political Role: Norba Caesarina served as an administrative and tax centre for a vast territory in the province of Lusitania.
In the early period, the region's economy was based on agriculture, cattle breeding, and trade, which flourished due to the proximity to imperial roads. The cultural landscape of the city changed radically in the 12th century with the arrival of the Moors. It was during the Arab period that the city received the name Al-Qazires, which translates as "fortress" or "citadel". The Moors rebuilt the Roman fortifications, erecting powerful walls and towers made of rammed earth, laying the foundation for the unique architectural ensemble that attracts tourists from all over the world today.
