The
Averno is made of a volcanic crater. Its tough nature
forced the lake to remain isolated and without residential
settlements until the end of the first century b.C.
The lake of Lucrino is closed to the sea and was
therefore characterized by a considerable urbanization
and an economic utilization since the beginning
of the first century b.C.
Slowly the Lucrino started being appreciated by
the Roman aristocracy because of its villas. In
37 b.C. they began to biuld the Portus Iulius and
therefore the istmus - that divided the Lucrino
lake from the sea and the Averno lake - were cut.
From the earliy imperial age until the fourth century
a.C. the Lucrino- Averno can be considered as a
unique huge residential and thermal site.
Thanks to its thermal natural sources, this area
was not forgotten in the middle ages. The Anjou
and Aragon courts did want to revalue the Phlegrean
therms. In 1299 Charles II of Anjou decided to buils
an hospital for the free aid for the poor people.
In 1538 many earthquakes that created the Monte
Nuovo damaged the baths and the warm sources, ruining
the intence tourism in this area. The Lucrino zone
was changed very much; it did not happen to the
Averno lake that on the contrary has been preserved
mysterious and solemn as it was seen by the ancient
writers .
