Citânia de Sanfins

Citânia de Sanfins is one of the best-studied sites of the Castro culture in northern Portugal. It lies in the parish of Sanfins de Ferreira, in the municipality of Paços de Ferreira, in the Porto district. The ruins of this ancient settlement cover about 15 hectares and show how people lived in the north-western corner of the Iberian Peninsula before Rome took hold.

What is a citânia?

A citânia is a fortified hilltop settlement typical of the Castro culture, shaped by the Celtic tribes of the region. Sanfins grew in several phases between the 5th century BCE and the 2nd century CE. Its main period of activity falls between the 1st century BCE and the end of the 1st century CE, when Roman influence was reaching the area.

What will you see on site?

The settlement was defended by three lines of walls, with an outer wall guarding the west and south and moats to the north and south. Everything was built from local granite blocks.

Inside the walls, archaeologists have found around 160 houses. Most are circular, about 5 metres across, with granite walls and conical roofs made of perishable materials such as thatch or timber. The houses are grouped into family compounds, several buildings around a shared courtyard. You can walk along the old lanes and look into the courtyards. One house was reconstructed in 1995, which helps you picture how it once looked. Near the entrance to the second wall stands a replica of a warrior statue.

On the edge of the settlement are the remains of a Castro-era bath complex. It had separate spaces for steam bathing and cold-water bathing, divided by a monolithic slab known as the pedra formosa.

How was the site explored?

The first excavations took place in 1895 under Francisco Martins Sarmento and José Leite de Vasconcelos, two pioneers of Portuguese archaeology. The last fieldwork was carried out in 1995. In the Middle Ages a Christian cemetery and a chapel dedicated to Saint Romão were established on the acropolis, adding another layer to the site's history.

The museum nearby

A short distance from the ruins, the Archaeological Museum of Citânia de Sanfins occupies an 18th-century manor house, Casa da Igreja, also called Solar dos Brandões. Its exhibition presents finds from the excavations along with material from across Paços de Ferreira, documenting human presence in the area since the Neolithic. Visiting the museum before walking the ruins makes it easier to understand what you see outdoors.
