Basilica dei Santi Silvestro e Martino ai Monti

One of Rome's historical treasures, located on the Oppian Hill (one of the spurs of the Esquiline). This church is particularly interesting for its rich, multi-layered history, including early Christian roots and a beautiful 17th-century interior. The basilica dates back to the 4th century and was built over ancient private houses (tituli) where the first Christians gathered. It was originally known as Titulus Equitii (after the owner of the house, Equitius). The church is dedicated to two important figures: Pope Sylvester I (4th century), associated with the era of Emperor Constantine, and Saint Martin I (7th century), a martyred pope. The main attraction of the church is its underground level, which offers a glimpse into the early Christian era. Here you can see the ruins of ancient buildings and experience the atmosphere of the first Christian gathering places. While the church's foundations are ancient, its current appearance is the result of extensive reconstruction carried out in the 17th century (primarily by the architect Filippo Gazoni) under the commission of Cardinal Alessandro Montalto. The magnificent 17th-century coffered wooden ceiling, richly gilded, is an impressive example of Roman Baroque decoration, though more subdued than in some other churches. One of the unique features of the interior is the 17th-century frescoes located in the upper portions of the walls of the central nave. They depict famous Roman churches and interiors, including Old St. Peter's Basilica. These paintings, created by masters such as Gaspard Dughet (Poussin's brother), are a fine example of Roman landscape art and a valuable historical record of what other churches looked like before their reconstruction. These experiences are unforgettable: the opportunity to descend into the crypt and see ancient Roman "tituli"—a unique experience that connects the visitor with the very origins of Christianity in Rome; The above-ground church displays the elegance and opulence of the 17th century, but with a special highlight in the form of frescoes that serve as a kind of "gallery of Roman architecture" of the period; located slightly away from the main tourist flow, the basilica offers a calm and contemplative atmosphere.

Beautiful as all the big ancient churches are here. The unique feature at this one is that you can see where they lowered the floor and added to the bottom of the columns, and you are allowed to go down more than three levels to the original street level from over a thousand years ago.

One of the most peaceful churches in Rome. It’s really old, dates back to the 4th century. I sometimes bring my clients here for photos if we’re nearby, especially in the morning when it’s quiet. The front of the church has this beautiful, old Roman feel that looks great in photos. It’s not crowded, the light is soft, and the whole place feels calm. Perfect for simple, natural shots with a bit of history in the background.

The basilica was founded by Pope Sylvester I on a site donated by one Equitius (hence the name of Titulus Equitii) in the 4th century. At the beginning it was an oratory devoted to all the martyrs. The interior has a nave and two aisles, divided by ancient columns. A votive lamp, made in silver sheet and housed in the sacristy, was believed to be St. Sylvester's tiara. Under the major altar are preserved the relics of Saints Artemius, Paulina and Sisinnius, brought here from the Catacomb of Priscilla. A mosaic portraying Madonna with St Sylvester is from the 6th century.

Basilica dei Santi Silvestro e Martino ai Monti is a very unique church steeped in history. The church itself is very detailed and intricate, but I really enjoyed the underground area which dates back to the 3rd century and can be explored. It was originally a house and the church was built over that house. It’s very interesting to explore the underground tunnels and rooms. There are a few faded frescos on the underground walls. The shell of the church itself was from the 9th century, but it was remodeled in the 17th century. Even though the major basilicas get way more attention, I really enjoyed exploring this gem.

Beautiful place and often skipped by tourists. Underground chambers from III century with early Christian paintings look stunning

Amazing historic church with underground levels. All passable for free, but I recommend a guide.

If the spectacular interior weren't enough, there are vast underground interiors whose entrance is found under the main altar - as well as a sweet, improvised exhibition of Nativity Scenes from many countries. But the Oscar definitely goes to the "albino" spiders on the spotlight in the lowest subterranean level - something I had never seen before! Ethereal music does the rest.
