You can see the old buildings, yet some parts are reconstructed for you to picture it as it was centuries ago.
I think it's important to take the historical tour inside the fort so you can listen to history events, the phases the fort went thru, and also the different uses of the fort. There are a few interesting stories about the prisioners of the Fort of Ulua.
If you like taking pictures, there are a lot of beautiful corners and angels. The sun and heat strikes the fort almost all day long, so take a hat and sunscreen.
