The Temple of Artemis Knakeatis is an ancient Greek temple dating from the 6th century BCE, located near the village of Mavriki in Arcadia, at the site called Psilí Ráchi on Marmarovouni Hill, at an altitude of about 1,250 meters. It was dedicated to the goddess Artemis. Today, only its ruins survive, which have nevertheless made possible a detailed reconstruction of its appearance.
The temple was constructed entirely from Doliana marble, named after the quarry located near the site of the present-day village of Doliana. It is believed to have been the first temple in mainland Greece built exclusively of this material. It was constructed in Doric order, belonging to the "Aeginetan School" of craftsmanship. Inside stood a large statue of the goddess Artemis, made of ebony, a small fragment of which has survived. The temple is also mentioned by the ancient geographer Pausanias, in his survired work "Description of Greece":
Archaeological evidence suggests that the worship of Artemis in the area dates back to the 8th century BCE.
