Impressive remains of the past, well prezerved today, even it is not much. You can visit it by paying 16,5 euro, but you will find no historical refferences about it inside the Park. Wich means you do your homework before, reading about it, or pay extra to hire a audioguide or a local guide. There are no curators in this superb site, you will not receive even a cheap map for your money.
