I often think Italy is too popular for her own good. When I pass through the piazza del Duomo in the middle of the day, on a nice day I can barely move through from the sheer numbers of tourists. The trash trucks and street washers (a type of vehicle) travel up and down the streets all of time, picking up after the people.
On the flip side, Italy reacts in general to the immense tourist population by constantly opening new sites to appeal to them. As someone who has visited Italy a lot over the past 30 years, I am constantly amazed when I learn new archaeological sites, for example, are newly available to be visited. As below.
