The floors of Roman buildings were often richly decorated with mosaics - tiny coloured stones (tesserae).
Many mosaics captured scenes of history and everyday Roman life.
Mosaic floors were a statement of wealth and importance.
Rich Romans decorated the floors of their main rooms with mosaics. These were stuck to the floor with mortar, a type of cement. Each mosaic used thousands of pieces to make a pattern.
