Santa Maria in Montesanto
This is one of the twin churches in Piazza del Popolo along with Santa Maria Del Miracoli. Built in the 17th century, this church includes the handiwork of three great architects. Started by Carlo Rainaldi, continued by Gian Bernini and finally completed by Carlo Fontana. Literally meaning the Holy Mountain, this is also called as the Church of artists because of the weekly mass conducted here by artists. Referring to Mount Carmel in Israel it is dedicated to the Virgin Mary. The two structures are considered to be twin structures because they look similar, but if you look closely you will find this one to be much different than the Santa Maria of Miracoli.
Santa Cecilia in Trastevere
This 5th century church is dedicated to Cecilia, the patron saint of Music. The church is lined with beautiful frescoes and late Renaissance architecture. One of the major highlights inside is the sculpture of St. Cecilia by the late-Renaissance sculptor Stefano Maderno. This sculpture seeeks to emulate the dead body of the saint. It also includes Pietro Cavallini's beautiful fresco in the nun's choir. You can also visit the excavations of the ancient Roman homes that are underway nearby.
Santa Maria Sopra Minerva
Crossing the Tiber we reach the Santa Maria Sopra Minerva. This Church is one of the main churches for the Roman Catholics and is the only Gothic church in Rome. It was built over the ruins of the temple of Minerva, the Greco-Roman Goddess of Wisdom and is thus called the Church of Saint Mary over Minerva. There are Renaissance sculptures inside the church, including Michelangelo's Christ Bearing the Cross. There are also various Renaissance and post-Renaissance tombs here.
