Estação Arqueológica do Prazo

Estação Arqueológica do Prazo is an archaeological site near Freixo de Numão, in the municipality of Vila Nova de Foz Côa, in north-eastern Portugal. What makes it special is the sheer depth of time on a single hillside: traces of human presence run from the Paleolithic through the Mesolithic and Neolithic to Roman and medieval times.

What is this place?

Prazo is best known as a Roman villa, occupied from the 1st century AD until the early 5th century. It was the residence of a landowner whose estate lay in the Douro region, and the finds show how a provincial elite lived far from the great cities of the Empire.

In the 5th century the main building was converted into an Early Christian basilica. The church and its cemetery stayed in use for a very long time, until the 13th century. Visitors can therefore follow how a country residence gradually became a place of worship and burial.

How old are the oldest traces?

Geoarchaeological research at Prazo identified an Upper Pleistocene sequence with Upper Palaeolithic finds. Fieldwork in the late 1990s, continuing until 2001, uncovered Neolithic layers and, beneath them, evidence of an earlier pre-Neolithic occupation. The site thus also documents the transition from hunting and gathering to early farming, and researchers relied on numerous radiocarbon dates to build the chronology.

How was it discovered?

The site came to light in the mid-20th century while almond trees were being planted. Intensive research followed in the 1980s and 1990s and into the early 21st century, largely thanks to archaeologist António Sá Coixão.

Protection and touring routes

In December 2024 the site was added to the "Romano a Norte" route, which highlights Roman heritage in northern Portugal. In 2025 the Portuguese cultural heritage institute opened a procedure to grant Prazo national classification, a sign of its importance.
