Geophysical and GPR studies were conducted in 2013 at Hadrianopolis in Paphlagonia, located in the Eskipazar District of Karabük Province. Based on the data obtained from these studies, excavation work was carried out on the remains of the Inner Castle between 2022 and 2023. The investigations revealed three distinct phases of construction within the structure according to architectural finds. The first phase involved a structure that served as a baptistery, constructed in the 5th century AD and remained in use until the 7th century AD. In the second phase, dated after the 7th century AD, significant structural changes were made. The original baptistery was divided into three different sections, each serving various functions. The final phase is characterised by walls close to the surface and a fountain transformed from a spolia sarcophagus. The quality of the structure, along with the fountain and coins recovered from the structure, suggests that this phase continued until at least the 10th century AD. The architectural stratigraphy indicates that the structure was in use from the 5th to the 10th century AD. However, due to damage caused by overlapping construction phases, a clear stratification of ceramic findings from phases I-III could not be established. This study covers 40 pieces of coarse pottery recovered from the baptistery. Although coarse ceramic findings are among the most frequently encountered forms in Hadrianopolis, they have not been sufficiently addressed in ceramic publications on the site. Therefore, this study can be considered a preliminary investigation focusing on forms identified as daily-use vessels, including khytrai, lekanai, jugs, amphorae, pithoi, and lids. Since no stratigraphy could have been established for the ceramic findings dating has been based on analogy. The primary aim of this research is to establish a typology for coarse ceramic finds in relation to Hadrianopolis and to determine whether the examples are locally produced or imported. The examples within the scope of the study were analysed based on their form groups. As a result of the study, it was observed that the majority of the findings belong to the Late Roman Period - Early Byzantine Period, although a few Early Roman Period forms were also identified. Additionally, the limited identification of similar types during the analogical analysis suggests that the variations in the clay colour and quality may indicate local production. However, this hypothesis will gain clarity through future clay analyses.
