Roman Ruins of Estoi

The Roman Ruins of Milreu are the remains of a large Roman villa in Estoi, a small town in the municipality of Faro, in Portugal's Algarve. It is one of the best-preserved Roman archaeological sites in the south of the country, only a short drive from Faro.

What is Milreu?

Milreu, also known by the older name Sambada or Sambata, is a villa complex founded in the 1st century AD. The estate grew over time. By the 3rd century the house had been reorganised around a large peristyle courtyard containing an extensive garden. The baths were decorated with mosaics showing marine scenes. The site also includes a temple, a mausoleum, and industrial and commercial buildings, which shows the villa was both a residence and a centre of agricultural production.

The temple and its afterlife

The most recognisable feature is the temple, dated to the 4th century AD. It was devoted to a water deity, and its walls carried a frieze of aquatic divinities. After the 6th century the building was converted into a Christian church, with a baptismal pool installed. It was later adapted for Muslim worship, and the courtyard served as a cemetery during the Muslim period. The villa was abandoned by the 10th century at the latest. In the 16th century a fortified rural house was built over part of the ruins, and its walls still stand beside the ancient remains.

Discovery and protection

The site was discovered in 1877 by the Portuguese archaeologist Estácio da Veiga. It is now protected as a national monument, and in 1992 it came under the care of Portugal's architectural heritage institute.

What to see

• Bath mosaics with marine motifs.
• The temple remains from the 4th century, with the later baptismal pool.
• The peristyle and garden, the heart of the former residence.
• A small museum at the entrance with a scale model of the temple in its heyday, which helps you picture the original building.
