The name ‘Fthiotides Thives’ was shared by two ancient towns in the area of Magnesia. One being near the village which is now called Mikrothives, and the other was near to the sea, in the port area of ancient Pyrassos, where today Nea Aghialos is, and reached the height of its development during the 6th century AD, being an important religious centre of the area. This is revealed by the excavations, which have brought to light important private and public buildings with marble statues and impressive mosaics as well as public streets, water reservoirs and baths, which are dated between the 3rd and 6th century AD. Very important findings can be considered; the big three-aisled basilicas with a vestibule, courtyard and buildings, which were decorated with mosaic floors, many of which are preserved in good condition thanks to the efforts of the archaeologists. The architectural remains of these churches which we see today in the archaeological area of Nea Aghialos, along with the large number of objects found in the excavations, prove the great acme of the area. Visiting hours: Daily 8:30 until sunset. Free entry
