The church was built between 1884 and 1888, designed by city engineer Francesco Agnesa, in an area that remained isolated from the rest of the city until the eve of World War I. The facade was designed on the model of Palladio’s basilica of San Giorgio Maggiore in Venice: divided into two orders corresponding to the nave and two aisles respectively, it features four columns with Corinthian capitals. The rectangular interior has three barrel-vaulted naves, side chapels and a semicircular apse. The church houses the 17th-century simulacrum of Our Lady of Mercede.
