I recommend that those who fly to.around and from Italy visit the avsim.com library and search FS2004 Scenery section by inserting in search box:"isd" please don't type in the inverted commas.
Exploring Italy in My DC3 recently I found the above scenery by the isdproject group to be excellent.
Additional scenery for Italy can be found by visiting http://walhalla.mine.nu/fs2004
FS9 Scenery Italy

Yes, walhalla has been mentioned quite some times now:
