New archaeological finds discovered underneath Greece's second largest city have been revealed to the media for the first time.

The findings in northern Thessaloniki came to light during the archaeological excavations earlier this month and were announced on national television.

They include well-preserved floor mosaics from the 4th century AD.

According to local reports, archaeologists believe the multicoloured mosaics belong to a large public building complex or urban villa.

Writes the filmer: "The mosaics under today's Egnatia Street, reveal the glamour, luxury and beauty that prevailed in Thessaloniki during the Roman period."

The excavation is still ongoing.

1600-year-old Roman Greek geometric design mosaics discovered in Thessaloniki, Greece. Impressive mosaic floors with geometric shapes of the 4th century AD probably belonging to a bourgeois villa, brought to light by archaeological excavation at the southern entrance of under construction metro station of Hagia Sophia, in Thessaloniki.

The mosaics under today's Egnatia Street, reveal the glamour, luxury and beauty that prevailed in Thessaloniki during the Roman period.

The multicoloured mosaics revealed, mostly with geometric decoration, are believed to adorn the flooring of the west portico stoa. Apart from the geometric shapes found in the surviving fragments of the mosaics, a woman's figure holding a child holds a separate position. The woman's face has been destroyed, yet it seems to be in a seated position, while the face of the little child stands out.

Thessaloniki, at the end of the 3rd and 4th centuries, became the capital in the context of the Roman Empire's quadriarchy carried out by Emperor Diocletian and acquired amazing infrastructure, with a huge palace that was not only the habitation of Emperor Galerius, as there were great personalities such as Constantine the Great and the Great Theodosius.
