As the Terrace of Tempe [n. 7] it was a long hanging garden, probably decorated with plants and pergolas. Nothing is known of its features because it has never been excavated and the antiquarian sources do not mention it.

At the southern end of the Terrace there is a secondary access to the Golden Square (n. 8), with the exedra PO55 and other rooms, that were at a lower level than the rest of the building.
