A new study of 8,839 ceramic fragments has strengthened evidence that Mellaria was a Roman mining center connected to major trade routes in southern Spain.
Researchers examined pottery recovered during archaeological campaigns in 2022 and 2023. They also reviewed excavation results from the area around Cerro de Masatrigo. Together, the evidence offers a clearer picture of Mellaria’s economy, water supply, and urban planning.
A Roman city tied to mining
Mellaria was located in present-day Fuente Obejuna, in Córdoba, Spain. The city developed in a mining region of Sierra Morena, an area that played an important role in Roman economic activity.
The study comes from the University of Córdoba’s Ager Mellariensis research project, led by Professor Antonio Monterroso Checa. Santiago Rodero, also from the University of Córdoba, Maudilio Moreno of the Archaeological Museum of Andújar, and Miriam González of UNED also took part in the research.
Pottery points to wider trade
The pottery record shows that Mellaria was not an isolated inland settlement. The city had strong commercial activity during the first and second centuries A.D.
Researchers found that imports reached Mellaria from Italy, Gaul, and North Africa. Many ceramics also came from Baetican workshops, especially those in Andújar and Córdoba.

The evidence confirms that Mellaria took part in the distribution networks of the Guadalquivir Valley. These routes helped move goods across southern Hispania and linked inland settlements with wider Roman markets.
Ceramics are key evidence for archaeologists because pottery was used in daily life and trade. Vessels carried, stored, and served goods such as food, oil, and wine. By studying where pottery was made, researchers can trace commercial connections across the Roman world.
Roads and water shaped the city
The study also documents major hydraulic and road infrastructure at Mellaria. Excavations around Cerro de Masatrigo gave researchers the clearest view so far of the city’s water system and urban organization.
The findings point to a planned Roman municipality supported by public works. Roads likely helped move people, minerals, and goods between Mellaria and other settlements. The water system would have supported daily life and may have served activities linked to mining and production.
Mining drove its growth
The volume’s editors said the material from Mellaria shows a pattern similar to nearby Sisapo. That connection suggests both cities shared trade networks and followed a development closely tied to mining in Sierra Morena.
Researchers said Mellaria reached its strongest commercial phase during the first and second centuries A.D. It later underwent a gradual economic transformation in late antiquity.
The study marks a major step forward in understanding one of the main Roman sites in northern Córdoba. It shows how mining, infrastructure, and trade shaped urban life in Roman southern Spain.
