The structures of the temple are later, though the presence of two Ionic capitals in the Museum (see under Museum), as well as of a Corinthian capital of the 1st century AD and other architectural fragments lead archeologists to suppose the existence of an earlier temple on the site.
As estruturas do templo son posteriores, aínda que a presenza de dous capiteis xónicos no Museo (ver baixo o Museo), así como dun capitel Corinto do século I d.C. e outros fragmentos arquitectónicos levaron aos arqueólogos a supoñer a existencia de un templo anterior no sitio.
