At an early stage, Corydala became the seat of a Christian bishop, a suffragan of the metropolitan see of Myra, the capital of the Roman province of Lycia.
In a letter to Amphilochius of Iconium, Saint Basil the Great mentions Bishop Alexander of Corydala as a champion of orthodoxy.
Palladius was a signatory of the letter that the bishops of Lycia sent in 458 to Byzantine Emperor Leo I the Thracian with regard to the murder of Proterius of Alexandria.
The present site is a village called Hacıveliler near Kumluca, on the east side of a small stream, about 16 miles (26 km), direct distance, south-west of Phaselis.
[8] There was discovered, in an old wall, a squared block, with its inscribed face turned towards the stones, on which, in beautifully preserved letters, was the name of the city—Corydalla.
