Recommendations for off the beaten path underground/ancient sites in Rome

Heading to Rome in July. My daughter is a huge Ancient Rome nerd (studies both Latin and Italian) and I love anything that highlights how people used to live not just the rich and famous. We both especially love seeing the “basement” rooms (old foundries/kitchens/plumbing/engineering marvels/tombs). So far I have the Vatican Necropolis and Colosseum Underground tours booked. We are the type of visitors who will read every informational sign and simply love exploring every nook and cranny we can find.. Looking for recommendations for those places that are not on the 3//4/5 days in Rome itinerary that would be interesting for people that love history and appreciate the smaller things when we travel. And maybe not so busy in the summer (hahahaha). We do have a special interest in exploring “underground”.

You sound like my kind of travel companions! Have you visited the Basilica San Clemente? I am unsure how crowded it will be, but it will certainly provide a welcome relief from the July heat to be 2-3 levels underground in the excavation areas.

One of our favorite underground sites is Domus Romana at Palazzo Valentini near Trajan's Column.
The archaeological remains of ancient Roman houses uncovered beneath Palazzo Valentini are now on permanent display.

We visited the catacombs of Priscilla. That is the only catacombs we have been to and, because it is in a less-visited area, we ended up having a private tour after we waited about 20 minutes to see if some other English speakers showed up and none did.

Near the Pantheon is Hadrian's Temple. Still having the original columns from one side of the buidling from year 145. It's cool to look at from the outside. But its free to go inside. There is a 20 min video inside that goes into pretty good detail about the history of Rome. It explains what Hadrian's Temple is, and then what it was used for throughout history. If you look on one of the columns you can see a cross that was made 1500 years ago when it was a hospital. It was really worth it, free, AC, and quiet. Only 3 other people were watching the video with us. I highly recommend it.

Two more ideas. One is literally underground, although not what you meant:.

Read all of the funerary inscriptions and their translations in the underground passageway between the two buildings of the Capitoline museum —- especially the ones for children. You will really get a feel for how the ancient Romans thought about family, fame, life, and death.

Try to see the swarming flocks of starlings in the evening through the open ceilings of the Baths of Diocletian.

On week-ends you could visit the Domus Aurea, Nero's Royal Palace that's underground near the Colosseum.

Another plug for the basilica San Clemente. Right near the colosseum. It’s a church built on a church built on a Mithraic temple.

There are also a couple of catacombs out of the Appia Antica.... which is a great "Ancient Rome" walk on its own, either for just a couple of miles or a few more than that.

St. Callixtus:

San Sebastiano:

Parco Appia Antica:

San Nicola in Carcere has some ancient Rome both underneath the church and visible from street level; there are exposed columns of 3 temples dating as far back from third century BC. incorporated into the exterior. The temples' bases are below ground, and can be visited during posted hours.

San Clemente is very interesting as it covers a number of different eras the further down you go.
However, don't bank on it being cool underground.
The Vatican Necropolis is humid, hot and stifling.
We didn't know this and brought warmer clothes that day to go there one June day.....big mistake!
Bring a hand fan, water, a cooling neck towel and a little spritz bottle of water to spray your face and neck.
Whew...we couldn't wait to get above ground again!
I don't know about San Clemente, as I was there on a cold weather day, and it's a lot more open lower down...not so closed in.

While it is not underground, have her check out Ostia Antica and see if it holds any interest for her. Easy to get there using public transit, and not usually crowded at all.

You seem like two people who would also like the National Etruscan Museum in the Villa Giulia --- it's one of my favorite museums in Rome.

Another vote for San Sebastiano! We enjoyed Catacombs of Priscilla but found San Sebastiano to be next level. The relics of Saints Peter and Paul were stored there. There are intimate chapels, very well preserved Roman tombs, in addition to the expected loculi. Casa Romane Del Celio beneath San Giovanni and Paolo is a collection of about twenty rooms from an apartment building and Roman houses. For me, a huge history buff, the Mamertine Prison was a big deal. You can go down into the holding cell to where the prisoners (many of high value) were held waiting for execution. They were dropped through a hole in the floor, which is still there.

I’m also interested in underground ancient sites. In 2018 I took a really interesting tour with Walks of Italy. Here’s the link for the current version of that tour which is called Crypts, Bones, and Catacombs: An Underground Tour of Rome.

In addition to the Capuchin Crypt, we visited a number of church catacombs (Priscilla and San Clemente among them).

Have fun planning your trip.
