Extensive Field Survey in North Central Bulgaria
The Roman city of Nicopolis ad Istrum and its territory lie in north central Bulgaria. Although the exact extent of the ancient city's territorial jurisdiction is unknown, in general terms the location of its fertile heartland is readily identifiable. The hinterland of the city was within the Roman province of Thrace from the foundation of Nicopolis c.AD 108 down to c.AD 193 when it was transferred to the province of Moesia Inferior. It comprised three distinct regions with different geographical characteristics. The southern part included the upland slopes of the Turnovo hills. The middle region, where the city was located, included the river valleys of the Rositsa and part of the Yantra while the third formed part of the agriculturally fertile light soils of the Danube basin. Within this area, survey has identified more than 300 settlements, dating from the first to the sixth centuries AD, all of which have been recorded as part of the national programme for the identification and description of ancient settlements.
