Cities' Answer to Sprawl? Go Wild.
In a neighborhood of right-angled stone, stucco and brick buildings not far from Milan’s central train station, two thin towers stand out. Green and shaggy-edged, they look like they’re made of trees. In fact, they’re merely covered in trees — hundreds of them, growing up from the towers’ staggered balconies, along with 11,000 perennial and covering plants, and roughly 5,000 shrubs.
