The Roman ruins of Tróia are located on a sandy peninsula, 10 minutes from the city centre. This site surrounded as it is, by the ocean, was once an important complex specialising in the production of salted and pickled fish. It was built in the first half of the first century and was occupied continuously until the sixth century.
Salt fish and fish sauces were prepared here drawing upon the abundance of fish in the Atlantic Ocean and the outstanding salt produced on the Sado River. These iconic products were then sold throughout the Empire.
The site gradually became a complex urban area. It was composed not only of many “salting factories”, but also of houses, other factories, thermal baths, and the mausoleum and necropolis characteristic of Roman civilisation.
Excavations carried out in 1956 uncovered Roman baths covering 450 m2. There are hot, temperate and cool water pools and an underground heating system, as well as a swimming pool and a sports arena.
This magnificent complex has been classified as a “Monumento Nacional” since 1910. It hosts archaeological exhibitions, guided tours, equestrian shows and other themed events throughout the year.
A timeless and unmissable place to visit, offering a real insight into the unique history of the Comporta region.
