Lake Bolsena

Lake Bolsena is the largest lake in the northern part of the region of Lazio in Italy and the largest volcanic lake in the whole country, having a circumference of 43km. It is known for a strange phenomenon, known locally as “sessa”, which causes tidal-like movements in the lake. Its formation began 370,000 years ago following the collapse of a caldera of the Vulsini volcano, which stayed active until 104 BC.
