Very unique and important archeological site and museum, and very cheap to enter. I do wish there was more written information, and that there was English or even Spanish included on the displays in the visitor center, but if you pull up the audio guide there are also English materials available for many of the displays (in the visitor center, the displays are only in Catalan). The full price of entry is only €5 (and that includes admission to the Archeological Museum too!!) so it's a VERY good deal and worthwhile if you have any interest in premodern history.
Also, the entrance to the museum is not located exactly where Google maps directs you to. If you are coming from southeast of the museum, you will pass the entrance on your way to the entrance where Google directs you.
