Yes, they are everywhere. I found many off the beaten path last year. A visit to the Cimitero Monumentale di Staglieno demonstrates this abundance. Since the mid-19th century, Genoans honor their deceased with elaborate marble carvings. There are likenesses, angels, and family members all preserved in stone niches. (1.5 miles north of Carrara; see 2sculpt.com for more pictures)
And then there is the home of Leonardo in the town, of course, of Vinci. There are replicas of his many inventions and most famous paintings. This modern steel sculpture is based on his sketch of human proportions. Obviously, I generally fit the model.
