I must admit I don't know much about the Italian campaign, but thought I'd post a few pictures of WWII sites I accidentally came across while visiting the Paestum archaeological site in Italy last week. Next to the hotel we stayed in at the beach was a park with a couple of monuments - one to US 36th Div and one to US 45th Div.
After googling "Paestum 1943" (apologies for my ignorance - I never realized the Allies landed so far south of Salerno!) I came across a photo of a stone tower and recognized it as the one right outside our hotel. It was used by German snipers during the landings. Here is a comparison between the photo from 1943 and one I took:
