The archaic period temple represents a development of Doric temple style, employing a elongated and narrow naos with an adyton at the rear and a pronaos with four columns. The spaces between the columns, or intercolumniation of the peristasis, were enclosed with high masonry barrier about half the height of the columns. In 1823, during excavations, two half metopes carved in tufa were discovered depicting Dionysus and Athena. They are now kept in the Museo archeologico regionale di Palermo.
