Sanitation, medicine, education, wine, public order, irrigation, roads, fresh water systems and this brilliant Ampitheatre. My advice for what it's worth, take the Panoramic lift, head up to the Castle and then view the Ampitheatre from above before entering this magnificent theatre. Hats off to the designers who create an excellent prelude of historic facts and artefacts over different levels before you enter the arena to a big fat Wow. I had to deliver the Monty Python sketch in the centre of the stage and can confirm that the acoustics are amazing even right at the back. So impressed as I was with this historic city as a whole. Well worth a couple of hours.

Nice to visit if you really like ancient stuff. In the museum you can see many every-day artifacts of the roman times. You can also have a closer look at the roman theater. However, you can just go to the free entrance of the roman theater and look at it from above. You see 95% of the theater, but for free.

Interesting visit to the amphitheater nestled in urban Cartagena. It was unearthed relatively recently, in 1998, during an excavation project. The amphitheater had been hidden beneath layers of modern development, including a bullring that was built over it in the 19th century. The excavation revealed not only the structure itself but also numerous artifacts that provide insight into the lives of those who once attended events there. The museum portion includes a view of the artifacts and history ending in the actual amphitheater. The contrast between the ruins and contemporary buildings is unique. Good activity to do when visiting Cartagena.

I've been to lots of Greek and Roman theatres. This one's glorious. Yes there's a lot of restoration but the museum is excellent and what's been recovered in Cartagena is spectacular. Go near sun down and you'll get some stinking pics
