Testaccio is a funky neighborhood located below the hills of the Aventine and across the river from the southern end of Trastevere. It was the site of an ancient river port. Most of the trading on the Tiber took place here.
The area, like most port towns was a little rough and tumble. Now it's the place for clubs, cool boutiques and of course the market. The market will be moving to a new location soon but the current one is worth checking out. The prices are not that much cheaper than Campo de Fiori, which is the market closes to me, so I won't be going often. I still need to visit the huge market near Termini.
Here is some very interesting information about Monte Tesaccio. This man-made mountain was formed during the height of the Roman Empire by the fragments of the clay containers used to import olive oil and other things.
I have no idea how to cook these but I want to try.
One of my favorite fruits.
Testaccio is hard core Roma (soccer) country. Do not roll up in this hood rocking your Lazio shirt. Ha.
