History
There are ruins of antiquity around the sinkhole. They were unearthed and surveyed by Victor Langlois and Semavi Eyice.
Pre Roman era
Kanlıdivane was a part of the Olba Kingdom in the ancient age. In the northern necropolis, there is a mausoleum, which was built by the Queen Aba for her husband and sons. On the inscription of the tower at south-west it reads;
"Built by Teukros, the son of priest king Tarkyaris of Olba for Zeus."
Roman era
By the first century, Olba kingdom became a vassal of the Roman Empire. Byzantine EmperorTheodosius II rebuilt the city as a Christian religious center and renamed it Neapolis.[1] There are ruins of basilicas, cisterns, rock cut graves etc. around the sinkhole.[2]
Kanlıdivane in popular culture
The current Turkish name Kanlıdivane may be a corrupt form of the ancient name Canytelis. It means "bloody crazy". It may refer to the red color of the surrounding soil. The name may also refer to a dreadful legend according to which the criminals had been executed by throwing into the sinkhole during Roman times.[3]
