Cuma's hill is composed by two terrace, the lower one is open towards east and encloses the ruins of Apollo's Temple.
Of the oldest temple, dating back to Greek period, only the steriobate stall of tufa remains, but nothing else remains of the elements of the colonnade and of the cell's structures.
It was probably a "peripter" temple built in the ruins of an older temple.
During the Augustan age Apollo's Cuman Temple was completely restructured to be later transformed into a Christian Basilica in the VI -
THE UPPER TERRACE OF APOLLO'S TEMPLE OR GIOVE'S TEMPLE
Giove's Temple is situated on the top of the "Acropolis".

Of the Greek age no architectural elements remain.
The steribate's "stalla" is almost completely hidden by the later Roman and Christian floor; no trace of the cell's and the colonnade's walls are visible.
