I have some lovely memories digging here, the site is really nice and definitly worth a detour, that is if you have you're own transport, don't bother trying to get here by means of public transport. Good and clear little museum. The site itself is rather large with only a small bit excavated, the main attraction here is what used to be the main square in Roman times, some of the pillars are still (again) standing there. Ammaia really has a lot of potential because at the end of the Roman era the site was abandoned and turned into agricultural land. But the site is run buy a non-profit organisation which has a really bad managment. And because of this the beautiful site whole probably always remain just a little spot only visited by archaeology fanatics.
