A water tank with mosaics, Milreu, Portugal, 2009. The ruins at Milreu are among the most important remains of the Roman presence in the Algarve and now form an imposing archaeological site, which has been classified as a national monument. The ruins consist of a manor house, farm buildings, a wine press, baths and a temple - a centre for private worship dedicated to the theme of the various water-based activities - which was built in the 4th century to satisfy the pleasures of the Romans. In addition to this, two mausoleums can be seen along with a peristyle with 22 columns, alongside an open courtyard with a garden and its attendant water tank.
