Life story
Leo IV was a Roman, the son of Radoald, raised and educated at the monastery of St. Martin near St. Peter's. Pope Gregory IV made him a subdeacon, and Pope Sergius II made him cardinal-priest of the church of the Quatuor Coronati. In 846 Saracen raiders attacked Rome and damaged many churches, including St. Peter's.
After Sergius II died, Leo was elected and consecrated on 10 April 847. He was consecrated without waiting for the emperor's consent, because the people feared for the city's safety after the raid. He repaired the city walls, rebuilt fifteen large towers, and was the first to enclose the Vatican hill with a wall, using imperial funds and contributions from the cities and farming colonies of the Roman duchy. The work took four years, was finished in 852 and was blessed by the pope; the enclosed district was called the Leonine City.
In 849 a Saracen fleet was destroyed off Ostia by the combined fleets of Rome, Naples, Amalfi and Gaeta, helped by a storm. Leo also repaired damaged churches, including St. Martin's, the Quatuor Coronati and St. Peter's. He died on 17 July 855 and was buried in St. Peter's; Benedict III succeeded him.
