Monte Nuovo ("New Mountain") is a cinder cone volcano within the Campi Flegrei caldera, near Naples, southern Italy.

A series of damaging earthquakes and changes in land elevation preceded its only eruption, during the most recent part of the Holocene, which lasted from September 29 to October 6, 1538, when it was formed.

[3] The eruptive vent formed next to the medieval village of Tripergole on the shores of the then-much larger Lake Lucrino.

The thermal bath village, which had been inhabited since ancient Roman times and was home to notable Roman-era buildings including Cicero's villa, was completely buried by ejecta from the new cinder cone.

Tripergole's ruins and its important thermal springs completely disappeared under Monte Nuovo such that the exact location of the village can no longer be identified.
