Facing the Nymphaeum it is located in a place that is the focus point of many aspects that shaped the nymphaeum over the centuries. The town in the background with the castle of the influential colonna family - for whom the structure was most likely built as leisure and naumechea spot. The topography of the lush valley gives the ruin its enchanted and sheltered ambience.
