This is an amazing site, worth spending some time.
From the Plaza del Armas bus station in Sevilla you get a local bus #172 at platform 16, for 1.4 € p/p. The bus takes about 30 minutes and goes and returns on the hour and half hour. The get off spot is at the turnaround for the bus to return to Sevilla. Sure makes it easy, and just a short walk to enter Itálica.
We passed through Camas, Huelva, and most of Santiponce, all really lovely towns, it would be nice to spend more time to explore them. So silly but every time I want to write explore, I automatically think exploor, and have to correct myself.
I must give credit and thanks to the movie industry, and to the TV industry that replays old movies. I've seen so many old roman, gladiator movies that it was so easy to picture in my mind the coliseum, the slaves and gladiators, and animals and the movements under the arena. And then the family spaces, I could see the rooms,with the large urns, flowing cloths to block sun and bugs, and the family relaxing in the inner courtyard garden with its flower and fruit trees. I REALLY enjoyed Itàlica.
