Ancient city of Knidos is located on the tip of the peninsula (about 30 km west of Datça, near the village of Yazıköy). Although not impressive as it used to be at ancient times, this city had the famous naked Aphrodite, chipped by Praksiteles of Athens. Long missing (only its pedestal is still on the site), this statue once generated one of the earliest forms of tourism: People from all over Mediterranean world flocked to Knidos with the only intention of seeing it. There are two amphitheatres in Knidos, one of the facing Aegean Sea, while other has a view of Mediterranean proper.
