Roman Ruins in Cartagena Spain: Uncovering Ancient Carthago Nova

Walking through the historic center of Cartagena (Spain), means walking directly above the footsteps of Roman emperors, consuls, and gladiators. Beneath the modern streets lies one of the most fascinating archaeological treasures in the Mediterranean: ancient Carthago Nova.

Here is your ultimate guide to descending up to 15 feet below street level to discover ancient temples, paved Roman roads, and monumental bathhouses.

From Modern Streets to the 1st Century: Why is Cartagena Underground?

Unlike ancient cities that were abandoned over time, Cartagena is what archaeologists call a stratified city. Over more than 3,000 years of continuous human settlement, different civilizations—Punic, Roman, Byzantine, Moorish, and Christian—built directly on top of earlier structures.

Urban expansions during the 19th and 20th centuries covered much of the ancient ruins. However, major archaeological excavations rescued in the late 20th century the history of Cartagena from obscurity.

Top 5 Roman Ruins in Cartagena Spain You Cannot Miss

👉The Roman Theatre of Cartagena: Augustus’s Masterpiece.

Discovered unexpectedly in 1988 beneath the ruins of an old cathedral, the Roman Theatre of Cartagena is the city’s crown jewel. Built between 5 and 1 BC under the patronage of Emperor Augustus, this massive structure could seat 7,000 spectators.

Your visit begins at the Roman Theatre Museum (designed by architect Rafael Moneo), where a subterranean vaulted corridor leads you directly into the breathtaking cavea (seating area) carved into the hillside.

Highlight: Standing in the arena and admiring the original marble capitals imported directly from the famous quarries of Carrara, Italy.

👉The Roman Forum District & Decumanus Maximus.

If you want to experience what everyday life felt like in ancient Carthago Nova, visiting the Roman Forum District (Barrio del Foro Romano) in the Molinete Archaeological Park is essential. It stands as one of the largest urban archaeological parks in Europe.

In this covered underground site, you can walk along the original stone paving of the decumanus maximus, view the remains of 1st-century AD thermal baths, explore the Atrium Building used for sacred banquets, and admire the Sanctuary of Isis and Serapis, dedicated to exotic eastern deities worshipped by Roman sailors.

👉Casa de la Fortuna: Mosaics and Chariot Tracks.

Curious about how a wealthy Roman family lived during the Augustan era? The Casa de la Fortuna offers an intimate glimpse. This 1st-century AD Roman domus preserves its key rooms perfectly beneath modern city streets.

As you step down into these underground roman ruins Cartagena preserves, you will walk through the central atrium, bedrooms (cubicula), and dining rooms (triclinium), marveling at preserved geometric mosaics, wall frescoes, and an external Roman street showing visible chariot rut marks worn into the stone thousands of years ago.

👉The Augusteum: Temple of the Emperor's Priests.

Situated near the historical harbor, the Augusteum was the seat of the seviri augustales, a college of priests dedicated to worshipping Emperor Augustus and the divine imperial family.

This vaulted underground hall features rich marble flooring (opus sectile) sourced from various corners of the Roman Empire, fragments of an imperial statue clad in a toga, and a sacrificial altar. It provides an fascinating look into Roman political propaganda and imperial cult worship.

👉The Punic Wall: The Prelude to Roman Conquest.

While originally constructed by Carthaginian general Hasdrubal the Fair in 228 BC, the Punic Wall of Cartagena is an indispensable stop on any Cartagena itinerary. It was right at these walls in 209 BC, during the Second Punic War, that Roman general Scipio Scipion Africanus launched his daring siege to capture the city for Rome.

The interpretation center also houses the 16th-century Crypt of San José, built right over the ancient Roman defensive moat.

👉Practical Tips for Your Self-Guided Roman Tour.
