Atop all those buildings, every single one of 'em, filling the skyline and squeezing for space, are hundreds and hundreds and hundreds, and I mean THOUSANDS, of aerial TV antennas. Cable TV must not be catching on too quickly here in this land of no clothes dryers and hundred-year-old paint jobs. Well. TV antennas. Having grown up in the cable and digital age, I haven't seen one that actually served its original purpose in years, and here they all are in Italy.
Just look up to the roof of any building and you'll see them, filling every available space and seemingly trying to point in every direction at once; immobile receptors, aimed by their owners to compete for the strongest wavelength that might happen to pass by, like endless fields of metallic wildflowers pointing toward the sun for the greatest hit of radiation they can withstand.
