Underground Rome · Archaeological Atlas

Places in Depth

An expanding atlas of archaeological spaces preserved across Rome at levels different from the city we occupy today.

Roman residences, sanctuaries, funerary complexes, water systems, ancient roads, service galleries and monuments incorporated into later architecture.

The Atlas

Rome survives at many different elevations.

There is no single archaeological level below Rome. Different districts preserve different periods, structures and former ground surfaces at different depths.

Some ancient buildings were filled deliberately. Others were incorporated into later construction. Street elevations changed, monuments were reused and entire architectural spaces became enclosed within a continually developing city.

This atlas documents those places individually. Together they create a physical record of Rome's transformation across more than two millennia.

Archaeological places across Rome.

Each entry examines one physical site: what survives, how the structures developed and how the archaeological evidence relates to the city around it.

Reading the Atlas

Not everything below ground began underground.

01

Original underground structures

Crypts, service galleries, cisterns, funerary spaces and certain sanctuaries were conceived below or partly below their contemporary ground level.

02

Architecture enclosed by later construction

Ancient rooms sometimes survived because subsequent buildings incorporated, filled or built directly over them.

03

Former ground levels

Some archaeological areas were originally open to the sky. They appear lower today because the surrounding city changed elevation.

04

A city still being investigated

Excavation, restoration and infrastructure projects continue to change what can be studied and understood across Rome.

Field Notes

From individual sites to the physical development of Rome.

Places documents individual archaeological locations. Field Notes examines the larger questions connecting them: changing ground levels, water, excavation, construction, ancient infrastructure and the processes that produced the city visible today.
