Romans and Byzantines were very careful about the protection of the capital. So they built port sites and military bases on Black sea coasts.

The archeological items show us that there used to be a port site around Kerpe (on the north). It is the sign of the important site for ancient era. A castle used to be there in order to protect the port. Archeologists think that it was built in Byzantine period.

The archeological items are massed up so an archeological work is necessary in the field.
