St. Sebastian catacombs:
The ‘memoria apostolorum’, ancient site where the early Christians pay tribute to the apostles, is part of the tour. Noteworthy are three hypogeal of the 1st century and epigraphs of the 5th century.
My favorite catacomb because of its beauty, history and significance. The location is within the walking distance from the Circus of Maxentius, the mausoleum of Romolos, the mausoleum of Cecilia Metella and the stroll along the Appian Way.
