Colosseum-Imperial Forums: new Metro C station

An underground museum in the heart of Rome

Get off at the new Metro C station - Colosseum–Imperial Forums It's no ordinary gesture. It's not just access to a subway line, but the beginning of a vertical journey spanning centuries of history. Step by step, the contemporary city gives way to ancient Rome, in a journey where infrastructure, archaeology, and architecture coexist in the same space.

The station, part of the Metro C, represents one of the most complex and significant interventions ever carried out in the capital's subsoil.

A unique place, above and below ground

The positioning of the station is extraordinary: between the Colosseum and Imperial Forums, in perhaps the most delicate point of the entire Roman urban fabric. Building here meant dealing with a continuous, dense, and fragile historical stratification.
Every meter excavated has yielded traces of the past: walls, pavements, ancient infrastructures, evidence that tells the story of the city's evolution from Roman times to the modern era.

The construction site as a place of discovery

The station construction site was, in fact, a huge archaeological excavation.
Each excavation phase was constantly monitored, each find documented, studied, and restored. The construction site thus transformed into a true scientific laboratory, where archaeological research and architectural design proceeded in parallel, mutually influencing each other.
The investigations brought to light:

imperial-era structures
medieval and Renaissance remains
pavement levels and ancient paths attributable to road layouts
hydraulic systems and overlapping walls

This required a constantly evolving design process, with archaeologists, engineers, and architects working side by side. Many decisions were made "on the fly," adapting the project to the discoveries, slowing down the work but greatly enhancing the cultural value of the work.

Archaeology visible, not hidden

The real strength of the Colosseum–Fori Imperiali station lies in the decision to do not separate infrastructure and archaeology. The finds are not removed or relegated elsewhere, but integrated directly into the station path.

The concept is that of a chronological descent:
The further you descend towards the platforms, the further back in time you step. The stratigraphy becomes part of the passenger's daily experience, visible through glass windows, walkways, and controlled views.

The wells

Vertical archaeology in the subsoil of Rome

Among the archaeological displays at the Colosseum–Fori Imperiali station, the shafts are among the most effective and subtle. They aren't intended to be spectacular, but they clearly illustrate how the subsoil of ancient Rome was constructed and organized.
At the station Metro C, the wells become reading tools, rather than simple exhibits.

Reassemble to understand

The wells visible today are not scenographic reconstructions, but philological recompositionsThe original stone elements, found during the excavations, were originally juxtaposed to form the vertical shaft. After being documented and studied, they were repositioned in sequence, respecting the original construction logic.
The result is immediate: the construction principle is read at a glance, without the need for mediation.

A natural dialogue with architecture

The verticality of the shafts interacts with that of the station itself, a space that leads the visitor on a gradual descent underground. Ancient and contemporary thus meet on a common ground: that of construction and gravity.

Archaeology that explains

These wells exemplify the approach adopted on the site: the find is not an isolated object, but part of a technical and scientific narrative. A simple and precise display that forgoes spectacle to restore knowledge.

The interior: a station that you walk through like a museum

The interior spaces are large, deep, and monumental. The project plays on:

large underground volumes
clear and legible paths
walkways suspended above the archaeological remains
glass walls that protect but do not separate
lighting designed to enhance materials and walls

Light, in particular, plays a fundamental role: it's not just functional, but narrative. It guides the gaze, highlights the layers, and transforms the artifacts into true display elements.

Moving through the station is not a simple transit: it is a slow, almost contemplative experience, which invites observation and understanding.

A new model of urban infrastructure

The Colosseum–Fori Imperiali station is much more than a metro stop. It's a concrete example of how contemporary mobility can interact with history without overwhelming it.

Represents:

an advanced model of archaeological station
an international case study
a meeting point between public transport, public space and cultural heritage

In a city like Rome, where every underground intervention is a challenge, this station demonstrates that it is possible to transform complexity into value.

Main dimensions (sources Metro C SpA / official communications):

maximum length in plan: 150 m
maximum width in plan: 34 m
depth: up to ~32 m
excavation volumes: ~172.000 m³ (of which ~29.000 m³ archaeological)

With the opening of the Colosseum–Fori Imperiali station, Line C does not stop, but continues towards Piazza Venezia, where work is currently underway on the construction of another station of exceptional complexity. Here too the project is confronted with an extraordinary archaeological stratification, confirming the vocation of the Line C as a mobility infrastructure but also as system of museum stations in the underground of Rome.

A photo gallery that tells the story of the city

Seen through a photo gallery, the station reveals all its strength:
the contrast between old and new, the depth of the spaces, the materiality of history that emerges alongside contemporary architecture.

It is a work that speaks on multiple levels: to citizens, to visitors, but also to designers, students, and scholars.
A station to pass through every day, but also to observe carefully, because beneath our feet Rome continues to tell its story.
