Rione Terra is the oldest quarter of Pozzuoli. It was built as a fortress on a large tufa rock. Until 1970, the quarter, with its narrow, ancient streets, was inhabited. It was evacuated due to a sudden bradyseism (ground uplift) that raised the hill by 1.7 meters above sea level. The quarter was further damaged by the Irpinia earthquake of 1980 and has been the subject of restoration and excavation work since the 1980s. In 2014, Rione Terra was reopened as an open-air museum. Currently, the restored areas are open to the public. The construction sites, including the cathedral, are closed to the public.

The entrance isn't where the pin is, but further down the main road. It's worth seeing, even though a large part of the area wasn't open to the public.

The Macellum of Pozzuoli is an archaeological site located in the municipality of the same name in the metropolitan city of Naples. Due to the dual interest it has, archaeological and scientific, it is one of the best-known monuments of the entire ancient world. The building has long been improperly called the Temple of Serapis, due to the discovery of a statue of the Egyptian god in 1750, at the time of the first excavations. Subsequent studies have instead ascertained that it is the ancient Macellum, that is, the public market of Roman Puteoli. In terms of size, it is the third most important Neapolitan monument of this type. On a scientific level, it has represented for some centuries the most precious and precise metric index available to measure the phenomenon of bradyseism.
