The church of San Rocco all’Augusteo, located on the Largo di San Rocco, in the Campo Marzio district, was erected by the will of the brotherhood of the Osti and the Barcaioli of Ripetta who, under Pope Alexander VI, had the task of rescuing the sick of plague along the banks of the Tiber. Built in 1499, on land adjacent to the Mausoleum of Augustus, this church was dedicated to the French hermit saint Rocco who lived between 1299 and 1327. The building was almost completely rebuilt in 1657 to a design by Giovanni Antonio de Rossi. The neoclassical facade renovated during the first half of the nineteenth century is a single order and is the work of Giuseppe Valadier.
