Bulgarian archaeologists discovered a unique, richly decorated, 1600-year-old mosaic during excavation works in downtown Sofia at the site of the ancient Roman city of Serdica. The mosaic, which was uncovered below a concrete supporting block under the central Dondukov boulevard, has six colours and is made of natural elements. Archaeologists suggest that the mosaic covered the floor of a central building belonging to the affluent citizens of Serdica, private bTV station informs. A hypocaust underfloor heating system made of hollow canals used for transporting air heated at a special furnace, was uncovered under the mosaic. The moisture under the concrete block presents the greatest challenge to archaeologists for the preservation of the mosaic. |
