The high quality, for example, of the 'Mosaico das Musas' - from a Roman villa in nearby Monforte (4th century BCE) - points to the abundant riches to be made as an Alentejo landowner in the Roman era. Sadly, many artifacts from Ammaia - in particular a series of marble sculptures - were removed during the 19th and 20th centuries, notably by the Anglo-Portuguese Robinson family. These items are now in collections such as those of the British Museum.[2]
