If you love ancient architecture, and in Rome all the forums, the Palatine and Apian Way, etc. , have already been studied, I advise you to come to Ostia Antica. Getting there is very easy. Metro to st. Piramida, and then take the train to Ostia Antica station. Cross the road over the bridge and you can see it there. We were in the summer and there is a lot of greenery, it's nice to take a walk, see ancient mosaics, sit on the stones of the amphitheater. I don't think a guide is needed, get ready from home, the territory is not very large, and everything is signed.→
