Hadrianoupolis is located 3 km west of the modern town of Eskipazar, near Karabük, in southwestern Paphlag- onia. Some of the ruins of the structures in the city have remarkable floor mosaics which are dated to the end of the Vth century and the first half of the VIth century A.D. These buildings with mosaic floors are the Baths ‘A’ and ‘B’, the Early Byzantine Churches ‘A’ and ‘B’ and an Early Byzantine Villa. Excavation studies of the buildings were conducted by a team directed by Assoc. Prof. Dr. Ergün Laflı from the Dokuz Eylül University in 2006 and 2007
