The complex is rather large, and there are plenty of things to explore. The circus is not there anymore, but the vault still exists, which is one of the longest ones of its type. It is 300 meters long, and a video visualization of the whole complex aids the visitor to see how everything fell into place back then. Nowadays, there's plenty of modern buildings co-existing with the ruins.
The pictures above show you the interior of the vault.
And of course there are remains of the ancient Roman culture, in the form of statues, pillars, and other items with Latin inscriptions on them.
Tarragona isn't probably the most known Roman site, but there's plenty to see for those who visit. There's more things to show, so stay tuned for my next post.
