Lu, who would appear to be cited in papers dating back to the tenth century, appears with security in an act dated October 3, 1028 , when Odda, her son Oddilo o Guido Lord of Monfalcone donate to the Monastery of St Peter in Savigliano a tenth of the court of Lu , with the houses , the sediments and every thing around it, two chapels , one that is in honor of St. Peter , the other of St. Benedict, with their equipment and appliances, and all they had in the places of Cuccaro and Mediliano .

The present village of Lu, on the high hill , was built in the Middle Ages , when after the Lombard invasion (VI century AD) the population of the Roman pago of Mediliano entrenched to defend itself , whence the name derived from the surname Lugus , god of the peaks to which the Celts dedicated the highest hills
In the plain of Mediliano on the right side of the river Grana , not far from the church of San Giovanni , the vast area preserves the remains of the Roman pago; coins of the first century BC were discovered frequently, remains that still crop up from the turf at each plowing autumn , tiles , tombs, cinerary urns , amphorae . Roman walls and artefacts are frequent
