Rione Terra is a historic quarter in Pozzuoli, Italy, in the Phlegraean Fields region west of Naples.
The ancient fortress originally served as the acropolis for the Greek settlement of Dicearkia before being integrated as the Roman port city of Puteoli.
The densely built-up district is located on a small tufa promontory overlooking the Gulf of Pozzuoli and today serves as a tourist attraction.
[1] Rione Terra was originally a fortress for the settlement of Dicearkia founded by Greek colonists from Samos in the 6th century BCE.
[1] With its narrow and ancient streets, Rione Terra was populated until 1970 when it was evacuated due to a sudden bradyseism event that raised the hill on which the district is located by 1.7 m (5.6 ft) relative to sea level.
