San Giacomo in Augusta, a Baroque Church in Rome, located on via del Corso in three blocks South of Piazza del Popolo, in the Campo Marzio. Next to it stands the Church of gesù e Maria.

The first Church on this place was built in the 14th century near the hospital for incurable patients (Incurabili) – it was called San Giacomo degli Incurabili. And the prefix "in Augusta" was added later, because of the August Mausoleum nearby.

That first Church and hospital were established in 1339 by the initiative of cardinal Giovanni Colonna. By the early 16th century, the hospital was abandoned, but a few decades later was re-opened under the patronage of two religious orders. It was assumed that it will contain patients with syphilis. Pope Nicholas V gave the hospital to the jurisdiction of the Florentine cardinal Antonio Maria Salviati, who initiated the reconstruction of the Church. Oval in plan the building was completely rebuilt under the project of Francesco da Volterra. Reconstruction began in 1592 and was completed in 1600, under the supervision of the architect Carlo Maderno, who worked on the facade and interior decoration of the temple.

The interior of the Church is remarkable bas-reliefs and stucco work by the French sculptor Pierre Le Gros the Younger, paintings Giuseppe o Passeri, the work of the artist-Mannerist Cristoforo Roncalli and other works of art.
