The inside stairs and the arches over the doors are made of large stone blocks. In some
places one can still see fragments of magnificent mosaics. They, together with numerous decorative fragments of marble,
the stone columns and capitals are indicative of the ornate decoration of the building.
Passing through the spacious halls that formed a natural barrier to the cold air, the visitors entered a large hall called balestra.
With its area of 840 square metres it was a unique centre where the citizens of ancient Odessos got together to discuss
important issues of public life. Even today people are curious to learn how its heating system was designed and worked.
It included a double floor and special hollows through which hot air reached up to the roof of the Baths. A host of little shops,
game rooms, halls for bathing in cold, warm and hot water, rest rooms - the visitors today can imagine what a busy life was
bubbling in the ancient Roman Baths.
