You’ve got to check out this basilica and especially the excavation beneath! You will pay a couple of euro to a man sitting near the sacristy who let you down the stairs into another world! A relatively new excavation with not a lot of monitoring or signage you can see the remnants of ancient art work the ancient pagan and Christian homes that the Basilica is built on top of, water cistern that probably served as a baptismal font, sarcophagi, etc. really amazing. Go!

This is a lovely church with an amazing crypt below, this is possibly the best 3 euros I spent. It is not clearly advertised that you can visit the crypt, just a small sign by the door, pay the man in the office, and he shows you the staircase down to the crypt. Lots of fragments of frescos to see and a coffin with some suspect bones in it. Highly recommended.

Did this saint exist? Under the church is an early 4th century auditorium and a Roman house. Before Constantine recognized Christianity in the 4th century, Christians only met secretly in private houses, certainly here too. Built in the 12th century in a new Romanesque style, the campanile was preserved. In the 17th century, the church was redesigned in Baroque style by Cardinal S. Caffarelli-Borghese, whose coat of arms can be seen. Here the largest columns in Rome support the triumphal arch. Outside the church, nature conquers the stone. My photos!

San Crisogono (it should be the only church in the world dedicated to this saint) is a large and ancient church (minor basilica), present in Trastevere (R. XIII), there is news of this church already in the 5th century. In the following centuries it underwent various restorations, the last most significant being that of the 17th century carried out on behalf of Cardinal Scipione Cappellolli-Borghese, whose name is engraved in large letters above the colonnade of the facade. The colonnade is made up of four columns of red porphyry, which support the cornice, where various sculptures of eagles, Borghesian griffins and vases are placed. The second order is set back, surmounted by a pediment on the sides of which there are two plumes and a cross at the top. On the right, still set back, there is a high square-shaped bell tower (measuring 8 meters per side and 45 meters high) in Romanesque style from the 12th century, on several orders with single and double lancet windows, at the top of which there is a spire, included in the restoration of the 17th century. The main entrance, located under the portico, consists of a beautiful portal, surrounded by a marble composition with pilaster strips and capitals with the engraving with the name of the aforementioned cardinal also shown here, all surmounted by a curvilinear pediment, with in the center the coat of arms of the Trinitarians. On the right side there is a very beautiful secondary entrance with marble ornaments, columns with capitals and a partial pediment since the Trinitarian coat of arms is placed in the center. The interior has three naves, delimited by twenty-two gray granite columns, the triumphal arch is supported by two large columns with Corinthian capitals. Of notable value: - The 12th century Cosmatesque floor, among the best preserved in Rome. - The majestic golden wooden ceiling, in the center is a painting of San Crisogono (copy from Guercino). In the main altar, covered by a canopy supported by four columns of Egyptian onyx, there are the relics of Saint Chrysogonus in an urn. In the apse basin in the center there is a mosaic attributed to Cavallini or his school (1290) which depicts "The Virgin and Child between Saints Chrysogonus and James". From the sacristy it is possible to access, by paying a small sum, the ancient Basilica, full of interesting archaeological and religious remains, for which I have carried out a separate review.

Make sure to visit the crypt--it's the best 3 euro you'll ever spend. The crypt is accessible from the sacristy in the front left of the church. When you go down the metal stairs into the crypt, you'll find yourself in the apse (near where the altar was). The main nave hasn't been excavated, so it's full of rubble and you can't see it. But you can walk to the left or right and follow the side ambulatories along the sides of the nave. The left side will take you past the baptistry and about halfway back along the church. The right side will take you the entire length of the church and into the entrance (vestibule, i guess?) of the church. I think the inscription says: Here lies a victor who lived 68 years, 11 months, 18 days. He was laid to rest on the kalends of January in the 14th year [of Emperor] Honorius [AD 409?]. May Theodosius [rest] in well-deserved peace.

In the heart of Trastevere is the Basilica of San Crisogono, built in the third century AD. on the title (i.e. on the original house) of Chrysogonus. The original basilica is located about six meters underground and was later rebuilt in the 12th century and then further modified in Baroque style by Cardinal Scipione Borghese. You can access the underground from the sacristy and you can see the remains of the ancient basilica with some ancient frescoes and other finds. In the upper basilica, the Cosmatesque floor and the mosaic in the apse, attributed to the school of Cavallini, are interesting.

The Church is among the oldest places of worship in the City, it dates back to the 4th century, internally built with salvaged materials, it has been modified several times. Among other things, the beautiful Cosmatesque floor is worth admiring.

What a hidden gem! They were so kind to let us view the crypt below the church with our teen daughters. We were absolutely blown away by the mosaics and frescoes and the ability to be up so close to ancient items.

You will not just enjoy the history and the spirituality of the church, you will experience a whole different level of happiness. At first as you enter the church you will see beautiful and deep details. As you go furthermore, you will see an example of Roman house structure. These are hidden gems 💎

One of the oldest in Rome. 4th century. Rebuilt later in 12th amd 17th. I was tired from a long walk and i missed the crypt. Info about the crypt isn't placed so that visitor can see it from the entrance.

Unfortunately not many people know this church but it is absolutely worth the visit as it is the 3rd oldest church in Rome.

Really interesting, was shocked to see the embalmed body inside

Seriously the coolest church in Rome. Go in the basement to the 2nd century church. Human bones are everywhere, and you’re alone only amongst the dead.

It may at first seem not as impressive as Colloseum, Roman Forum but...I would definitely put it amongst the most important landmarks of Rome. The story of the underground church is incredible. Only to mention it's the oldest church in Rome. You could argue Christianity started there. You must ask for Father Agostino. If he will have time, you are going to get the most amazing tour.
