Current location of Gairo is due to a flood in 1951 that forced people to abandon the old village and to build a new one. The move was completed in 1969. Part of the population of the old village was other wise forced to move to the lowlands and built the village of Cardedu (municipality on its own since 1984).The old village is still located 2 km south from the new one. It is a village dating back to the 14th century and it is known as Gairo Vecchio. It is one of the most famous abandoned places in Sardinia and in Italy.
