The most outstanding buildings in Philippopolis from the Roman period had richly decorated floors, usually with big mosaic compositions. Many mosaic floors of this kind have been found on the territory of the ancient town. The earliest mosaics date back to the 2nd c. but the findings of the 4th and 5th c. are the most numerous. Especially noteworthy is the floor decoration of a rich Philippopolis home that existed from the end of the 3rd till the end of the 5th c. Nearly 700 square meters of this remarkable building have been studied.
