Once the breeding grounds of mosquitoes that carried malaria, those mosquitoes were the true cause of the so-called Roman Fever that was romanticized in 19th century literature. The swampland was drained under Mussolini, and Latina was founded as a model fascist city.
I visited the city south of Rome last year for a running race, and wrote about this interesting place to visit.
The lake is located just along the sea, between the city of Latina and coastal Latina (Lido di Latina) is called Fogliano Lake. It is the biggest of four coastal lakes in the Pontina region, and it is part of the humid zone of the National Park of Circeo.
Afterwards, we continued the short distance to the seaside, walked on the deserted beach (the advantage of seaside visits in February), and stopped for a seafood lunch along the beach.
