I saw this ancient garden when I climbed the Palatine hill that is 40 m high. It wasn't easy but I got on the hilltop. Approaching closer to bushes I was looking for a potable water spring and I found a garden next to it.
Later I learned the legend that on the hilltop near this ancient spring there was a cave where Romulus and Remus were found by the she-wolf that kept them alive. Having grown Romulus decided to build a new city on the banks of the river Tiber. This is how "Rome" got its name - from Romulus.
Possible in those times a small garden could have been planted by them. There are fruit trees, bushes, grasses, roses, a pond and a small fountain. I think the Romans used water from a spring for watering the garden.
This accurate restoration shows us an ancient garden and the experience of ancient Roman gardeners.
