Torre Flavia Marsh is situated between the coastal resort of Ladispoli and the small town of Cerveteri, in the heart of Etruscan country.
The Oasis, assigned Natural Monument status in 1997, covers around 40 hectares and its main feature is a swampy area of great importance, acting as a habitat for migrating birds and because it is one of the rare remaining examples of Lazio’s salt marshes.
It is named after an ancient watchtower, Torre Flavia, probably built around the 16th century to defend the coast from Saracen raids.
As a result of coastal erosion, today the tower stands 80 metres from the shore, with its enormous ruins offering a suggestive view as it seems to emerge from the water, given that it is only connected to the land by a small jetty.
Finally there is also a fish breeding facility, as fishing has been practised here since Roman times, when they erected a villa with fish breeding pools, traces of which could still be spotted a few years ago though they are now covered by the sea.
