Chiesa di Sant'Isidoro a Capo le Case

The Church of Santa Maria della Concezione dei Cappuccini, built between 1626 and 1631 by order of Pope Urban VIII (1623-1644) to house the tomb of his brother Antonio Barberini. The building houses a popular crypt-shrine decorated with the bones of about 4000 Capuchin friars, collected between 1528 and 1870 in the former cemetery of the Capuchin order, which was located in the church of Santa Croce e Bonaventura dei Lucchesi, near the Quirinale.

The Church of the Holy Trinity of the Mountains is one of the five French-speaking Catholic churches in Rome, along with St. Louis of the French, St. Nicholas of Lorenese, St. Ivo of the Bretons and Saints Claudius and Andrew of Burgundy. The first part of the church was built between 1502 and 1519 in Gothic style. A new building was added to the Gothic nave in the mid-16th century, covered by a barrel vault and closed by a façade decorated with two symmetrical bell towers, the work of Giacomo della Porta and Carlo Maderno.

The Basilica of Sant'Andrea delle Fratte was built between 1653 and 1662 but a church already existed on the site in the 11th century. The Baroque reconstruction of the 17th century is the work of Francesco Borromini, but the façade dates back to 1862. The church is the place where the famous conversion of Alphonse Ratisbonne (1814-1848) took place.
