This is a Roman site, but it does also have remnants of an Iron Age settlement.






Most of the site is of Roman construction (1st century AD/CE), but there are remnants of earlier Iron Age buildings. Pottery from the Chalcolithic period was found on the site, indicating continued occupation from prehistoric to Roman times.
Other prehistoric settlements have been identified nearby. A Paleolithic site is 300 meters north of the villa, and another from the Chalcolithic lies 200 meters northeast. Two Bronze Age settlements have been found slightly further to the south. The Roman Villa itself seems to have been first occupied during the Iron Age, with continued occupation through the Roman era.
Some of the artefacts found on the site are housed in the Municipal Museum in Cascais, including an Iron Age carved figurehead of a dog:
