Lake Vico
Encyclopedia
Lake Vico is a caldera lake in the northern Lazio region, central Italy
. It is one of the highest major Italian lakes, with an altitude of 510 m. Administratively, it is part of the municipalities of Caprarola
and Ronciglione
.
The lake is surrounded by the Cimini Hills
, in particular by the Fogliano (965 m) and Venere (851 m) mountains. It is part of the Lake Vico Natural Reserve.
According to legend, the lake was created by Hercules, who defied the local inhabitants to wield his club. When he did this, a stream sprung up and formed the lake.
Lake Vico occupies the central caldera
of Vico Volcano. A volcanic cone
was built up in a series of eruptions that occurred between 305 to 258 thousand years ago. Later, the eruption of voluminous pyroclastic flow
s and volcanic ash
caused the progressive collapse of the volcanic cone to create the caldera, in which Lake Vico now lies, by about 138,000 years ago.
The lake is drained by the River Vicano. Before the construction of a tunnel by the Etruscan
s, the lake was probably deeper than today, the Monte Venere constituting an island within it.
The area is famous for its extensive beech forest, which is one of the most southerly in Europe. The elevation, plus the surrounding sides of the crater, create cool enough conditions for the continued survival of the trees. A large part of the northern side of the crater is a nature reserve to protect this forest.
