No precise birth date exists for Perdasdefogu. If historic certainties are unclear, oral tradition maintains that the village was founded by people from a coastal village of the Sarrabus region destroyed by the Barberians.

On the village territory is a wealth of pre-nuragic and Nuragic settlements. The most interesting among them are the domus de janas of Giuanni Puddu with its nuragic fountain and Sa domo de s’Orcu, the nuraghi of Tueri, Sufelissiu, s’Orcu and the megalithic monument of Su Perdiargiu (22 archaeological sites are located within the boundaries of Perdasdefogu).

The village jewel is the parish church of S. Sebatiano, located up-town. Art historians place its construction between 859 and 1000 A.D.. the temple is a three-nave construction reminiscent of the architectural structure of Asturias and Catalogne churches in Spain where the main nave and its three inner niches are separated from the other two by a series of arches.

The territory is quite interesting from a geological (Jurassic era), as well as botanical point of view and has been for years the object of frequent scientific expeditions from various Italian and European universities (in particular from France and Germany), as well as of experts from prominent British natural museums under the supervision of the British Council.

Nature lovers can visit the park of Bruncu Santoru. Itineraries  and directions are available. The countryside around the village is ideal for long walks in  the forest of evergreen oaks and along the rivers Sa Luda and Luesu (waterfalls, grottoes rich in stalagmitic and stalactic concretions). The countryside attracts fresh water fishing fans.

The village is decorated with mural paintings that illustrate episodes from its old and recent past, like the launching of missiles from the nearby base and their retrieval with local oxen-led carts.
