This church was built inside the former baths of Diocletian. Very light and airy inside. Note the unusual art on the outside doors. Around solar noon check out the sun's image on Francesco Bianchini's meridian line inside.
The Basilica of St. Mary of the Angels and of the Martyrs is a Catholic titular minor basilica and former Carthusian conventual church in Rome constructed in the ruined frigidarium and tepidarium of the Roman Baths of Diocletian in the Piazza della Repubblica.

On the site of the Roman baths this museum houses an enormous collection of statues, etc.
A magnificent collection of ancient Roman sculptures, mosaics and wall paintings, including the famous paintings from the Imperial-era villa discovered under the Villa Farnesina, as well as the dining room from the Empress Livia's villa at Prima Porta. Located across the piazza from Termini, opposite the Baths of Diocletian.
Now invaded by readers of Dan Brown's Angels and Demons, this is an interesting Baroque church containing Bernini's "Ecstasy of St. Teresa". Either side of this chapel are characters in what can best be described as theatre boxes. These are members of the Cornaro family, who paid for Bernini's sculpture. (As of Feb 2015, not visible due to restoration work.)
More modern than most Roman churches: it was not started until 1873. This is Rome’s Episcopalian church. Some very interesting artwork, particularly the mosaics by Edward Burne-Jones of the Pre-Raphaelite school.
Mura serviane
Remains of the first city walls, built in the early 4th century BC and attributed to king Servius Tullius.
Four fountains from the time of Pope Sixtus V when much of Rome was redeveloped. A reclining deity is the theme of each sculpture. This is a busy intersection and if you don't look twice you may miss these exquisite examples of Roman mythology.
