Sant'Omobono Archaeological Area

Brief information

Sant'Omobono looks like a small archaeological site by a church, but beneath it lies one of the earliest stone traces of Rome's religious life. In 1936, construction work accidentally uncovered the remains of sanctuaries associated with the temples of Fortuna and Mater Matuta in the Forum Boarium.

The main shift in perception comes from the lower layer: beneath the foundations of these temples, an even older, smaller temple from the 7th-6th centuries BC was found. Today these are the oldest known remains of a stone sanctuary in the territory of Rome. The source text connects it with the early port: the temple stood directly on the bank of the Tiber, and later the riverbed shifted west because of reclamation works. As a result, the site reads not only as a place of worship, but also as a trace of a city that grew from river trade.

What to notice first

It makes sense to compare two timelines: the paired temples on a shared podium and the earlier temple beneath them. The temples of Fortuna and Mater Matuta stood almost side by side and were nearly identical: each had a cella, that is, an inner chamber, and a pronaos with antae and two columns between them. This symmetry helps you see the later order of the site, rather than just a scattering of foundations.

The contrast comes from preservation and overlaps. Most of the foundation of the temple of Fortuna is exposed, while the remains of the temple of Mater Matuta are largely hidden beneath the present church. In front of the temples were two altars, and between them a round platform for votive offerings. Below lay a smaller temple with a different orientation: this change in direction shows that the place was not simply repaired, but reinterpreted several times. The later travertine paving adds yet another visible layer of rebuilding.
