Basilica di Sant'Agostino in Campo Marzio

The Basilica of Sant'Apollinare was founded by Pope Hadrian I around 780, on the remains of pre-existing Roman buildings. The original building was preceded by a small portico and, inside, it was divided into three naves with an apse. It was then rebuilt in its present form by Ferdinando Fuga on the orders of Pope Benedict XIV between 1742 and 1748: the same pontiff consecrated the new church on 21 April 1748.

The church of San Luigi dei Francesi was built between 1518 and 1589 by the French community of Rome. The work was carried out by Domenico Fontana on a project by Giacomo Della Porta, and thanks to the donations of Catherine de' Medici (1519-1589). Between 1749 and 1764 the interior was renovated under the project of the French architect Antoine Dérizet.

The church of Santa Lucia della Tinta is a small church, first mentioned in an epigraph from 1002. In 1664, the church was rebuilt, and at the beginning of the 18th-century changes were made (high altar and façade). In 1911, the church floor was redone. Since 1824, the church has been under the care of the Roman Curia.
