This title is the Bulgarian contribution to the European project for preparation of a map of the Roman Empire (composed of 56 sheets in scale 1:1 000 000). 'Sheet K - 35/2 Philippopolis' comprises approximately 75,000 sq. km of the territory of the Republic of Bulgaria, which is circa three-quarters of the country's area. Under the guidance of Prof. Rumen Ivanov, a team of 50 scholars - archaeologists, historians, philologists, ethnologists and cartographers - describe more than 1,600 modern settlements with more than 8,000 Thracian, Hellenic, Roman and Late Antique sites. The chronological range is from the beginning of the 1st c. to the beginning of the 7th c. CE.
