The 16-km-wide Bolsena caldera containing Lago di Bolsena, is the most prominent feature of the Vulsini volcanic complex NW of Rome. The 2,000 km² volcanic complex also includes the Latera caldera to the west. Both calderas were formed during the Pleistocene. Post-caldera eruptions produced scoria cones, lava flows, and youthful-looking cones that form islands in Lago di Bolsena.
