The dam is in front of the roundabout at the top of the hill. Praia da Luz also had its Roman settlement and part of it was excavated close to the beach on the Ocean Club garden phase. Archaeologists found a factory where shell fish were converted to a fish sauce in large tanks cut into the ground. If the fish sauce still popular in Asia is anything to go by the smell must have been terrible. Beside the modern marina at Vilamoura a Roman house has been excavated and preserved.
Visitors are welcome to visit the site which is kept well tended by the towns developers.
The house stood on a slight hill loking out across what was then an estuary. Archaeologists have found that the sea level was higher 2000 years ago and the area must have been a large sandy lagoon. Here again tanks were found for the salting of fish so it was probably an important local industry. Although the site has wells there is a dam two miles to the north so there is probably a larger settlement waiting to be found. The house obviously covers a large area and must have been an important residence.
