Here's a cool website with a very complete listing of Italian horse breeds. The breeds are listed in the menu on the left side. Clicking each will give you a description (in Italian, of course) [update: a reader points out this listing is now available in english at this link] and photos (usually towards the bottom of the page). There is quite a diversity, from mountain ponies to saddle horses and draft horses. Many of the saddle horses derive from combinations of Iberian, Arabian and Thoroughbred blood. Worth a browse, even if you don't speak Italian.
