The temple's dating is very uncertain, but it probably belongs to the middle of the sixth century BC.
The temple has six columns at the front and fourteen on the flanks and represented a development of the very elongated archaic temple to a more balanced form which was becoming the norm on the Greek mainland as well,[1] and foreshadowing the 2:1 intercolumniation ratio between the long and short sides.
The colonnade contained a wider pteron than usual in temples built in Sicily and, as a result, a rather narrow naos with an adyton at the rear and a pronaos with four columns.
[2] The barriers are about half the height of the columns and were perhaps built in a second phase of construction, perhaps in order to transform the peristasis into a cultic area.
[3] In 1823, during excavations, two half metopes carved in tufa were discovered, depicting Dionysus and Athena respectively.
