Blessed Ludovica Albertoni (Italian: Beata Ludovica Albertoni) is a funerary monument by the Italian Baroque artist Gian Lorenzo Bernini. The Trastevere sculpture is located in the specially designed Altieri Chapel in the Church of San Francesco a Ripa in Rome, Italy. Bernini started the project in 1671, but his work on two other major works—The Tomb of Pope Alexander VII and the Altar of the Blessed Sacrament in St. Peter's Basilica—delayed his work on the funerary monument. Bernini completed the sculpture in 1674; it was installed by 31 August 1674.

San Crisogono is a church in Rome (rione Trastevere) dedicated to the martyr Saint Chrysogonus. It was one of the tituli, the first parish churches of Rome, and was probably built in the 4th century under Pope Sylvester I (314–335), rebuilt in the 12th century by John of Crema, and again by Giovanni Battista Soria, funded by Scipione Borghese, in the early 17th century. The area beneath the sacristy was investigated by Fr. L. Manfredini and Fr. C. Piccolini in 1907. They found remains of the first church (see below). After they had made this discovery, the area was excavated and studied. The church is served by Trinitarians.

The church of San Cosimato is a church located in the city of Rome, Italy. It was originally built in the 10th century in the Trastevere rione and now includes the hospital known as "Nuovo Regina Margherita." Originally, it was built as a Benedictine monastery dedicated to Saints Cosmas and Damian, from whom it derives its name, and it carried the added designation of in mica aurea (“in the golden sand”) due to the presence of fluvial sand of yellowish color. The monastery was transferred from the jurisdiction of the Benedictine Order to that of the nuns known as the Recluses of Saint Damian (Recluse di san Damiano). From 1233, the church served as a hostel. Pope Sixtus IV had the church and monastery rebuilt in 1475, and after 1870, the convent was converted into a hospital. The façade of the church looks upon a public square that is also called San Cosimato. The church has a small Romanesque bell tower. The presbytery contains a fresco called Madonna and Child between Saints Francis and Claire, by Antonio del Massaro.

In 1533 the Confraternity of Genoans was founded to administer the church and the hospital - the latter continued to function until the mid 18th century. The church was rebuilt in 1737, with an apse added to its facade. It was then little altered until the mid 19th century, when a new facade was added and the interior redesigned. In 1890 the confraternity was renamed Opera Pia.
