With the arrival of the Turks in Anatolia at the end of the 11th century AD, it came under Turkish rule. Roman-era artifacts can still be seen in Kremna Ancient City. The city is surrounded by 2 meters wide, 7-8 meters high walls. The city was laid out in a grid plan.
Kremna Ancient City consists of structures such as the Acropolis (Upper City) with its Forum, Basilica (Courtroom), Church Elsodra (Arched Structure), and Library. In addition to these, there are the Propylaeum (Monumental Entrance Gate) and the Nymphaeum (Monumental Fountain Building).
The first detailed examination of Kremna Ancient City was carried out in the 1880s by the Austrian researcher Graf von Lackoronski, and he also prepared a plan showing the general condition of the remains of the ancient city.
Between 1971 and 1973, scientific excavations were conducted by Jale İnan, a professor of the Archaeology Department of Istanbul University Faculty of Literature, and the library building was uncovered. Nine marble god statues and other artifacts found during the excavations are now exhibited in the Burdur Museum.
