The Aghia Sofia metro train station of Thessaloniki may still be under construction, but it is already under way to becoming a museum.

As it has often been the case in most of the works for metropolitan underground railways in Greece, works revealed archaeological findings – in this case, mosaic floors dating from the 4th and 5th centuries AD.

The tiles, bearing impressive geometric designs, are to be detached and preserved, so that they can be put on display, once the station is open.

The Central Archaeological Council, which is to suggest a proper place to display the findings, also decided to showcase an ancient underfloor heating system, also found in the area in excellent condition.
