Once known as Stabia, Stabia, and finally Stabbia Castrum, Faleria owes its ancient name to the "Stabulum" ie an old horse-changing station, which was located on site.
Some people anyway think that the name of the town derives from "stabilis", with reference to its tuff foundation. The present name dates back only to 1873.
The first human settlement occurred in the area surrounding the tuffaceous rock called "Rocchetta", located under the Casaccia Footer Castle
Within this area in fact were found many traces of human settlements, many of which date back to the archaic era.
News of the feud Stabia are reported in some official documents of the Popes John XIX and Benedict IX. At that times Stabla was considered a fief and was formerly owned by the Anguillara, who kept it until the seventeenth century.
A date remains famous: November 1, 1504, when Girolama Farnese, wife of Giuliano Anguillara, was suspected of attempting with the help of her lovers, to poison her own son, Julian.
When the Anguillara family built their own castle, the village took on the appearance of a fortified settlement until, in XVI, the town expanded more and it was necessary to establish a new boundary wall.
In the second half of the seventeenth century all assets of the Anguillara, including Stabia, were sold to Prince Borghese.
In the nineteenth century the village still had its walls which were built some centuries before, but outside it the new village began to settle.
In the twentieth century the Renaissance walls were demolished and the Town Hall was built.
Finally, between 1971 and 1973 the old village was completely evacuated because of a high crash risk.
