An inscription of the fifth century BC attests the existence of an altar dedicated to Apollo and to the deities of the Apollonian trinity, Artemis and their mother Leto.
The Temple of Artemis is in the central area of the Sanctuary of Asklepios, where a pedestal inscribed with the goddess’s name stands in situ. It had an open entrance (pronaos) with six Doric columns and a cella with Corinthian colonnade on the three sides. It is suspected that the cult statue of the goddess stood at the centre of the cella. To the east of the temple is an altar and preserved a short distance to the north is a circular base for the perirrhanterion, the basin that held water for purificatory ablutions.
The temple was constructed of poros stone and limestone. On the outside was a Doric entablature. The roof tiles, the simas and the akroteria were of Pentelic marble. At either end of the long sides of the sima (the upturned edge of the last layer of roof tiles) were relief ornaments in the form of acanthus flowers. There were also waterspouts in the form of a dog’s head, because the hound was Artemis’ sacred animal-companion, while at the four corners of the building they were in the form of the head of a boar, because this was the goddess’s usual prey. Each of the two pediments had a marble akroterion (decorative sculptures) in the form of a winged Nike at the ends of the lower angles and a different akroterion on the apex.
