It was during the Roman period that this region developed and gained standing. It was then known as Civitas Ossobonensis, with its borders stretching to where modern Tavira lies, and included a number of towns with specific productive, rural and maritime functions.
This historical past come from interpreting archaeological finds made in the city which can now be seen in the Infante D. Henrique (Prince Henry the Navigator) Archaeological Museum, and the Milreu Ruins to be found in the suburbs of Faro.
The sheer beauty of the Ria Formosa Natural Park ensures it is well worth a visit.
