The Roman Ruins of Milreu represent one of the most significant Roman archaeological complexes in the Algarve, dating from the 1st to 4th centuries AD. This luxurious villa was the seat of a wealthy family and includes well-preserved thermal baths, living quarters, and an impressive temple. The main attraction is the stunning floor mosaics depicting detailed marine scenes including fish and sea creatures. The site is located in the peaceful village of Estói, ten kilometers from Faro's center, and can easily be combined with a visit to the nearby Palácio de Estói.
