A friend has a fantastic rooftop garden in New York, but unfortunately it is so high up you can’t spot it from the street. Not so in Rome. Yesterday, as I wandered the streets I used to roam as a kid, my eyes (and camera) kept flicking upward. Greenery was everywhere peeking above tiles roofs and spilling over parapets. Here are a few of the gardens that float above the streets of Rome. And don’t forget to check out the Battery Rooftop Garden blog to catch a glimpse of what beauty floats, unseen, above the streets of Manhattan.
