From Ruins to a Roman City: 30 Years of the Carnuntum Archaeological Park

Three decades ago, on June 9, 1996, the Carnuntum Archaeological Park was officially opened. What is now considered one of Austria’s most impressive archaeological experience and exhibition sites did not, however, come about overnight. The park is the result of a long process marked by extensive research, challenges in heritage preservation, and innovative approaches to managing ancient heritage.

Carnuntum was always more than just a site of Roman ruins. It was simultaneously a research site, a monument, a museum, a quarry, a place of longing, a destination for day trips, and a scientific challenge. The founding of the Archaeological Park thus marked not only the beginning of a new chapter for visitors but also a fundamental shift in how one of Central Europe’s most significant Roman archaeological sites is managed.

Carnuntum continues to hold a special place in Austrian archaeology to this day. Because the ancient urban landscape was not permanently built over, an exceptionally large research site has been preserved here. The potential of this site was recognized as early as the 19th century: Carnuntum was systematically investigated, established as a museum with the opening of the Museum Carnuntinum in 1904, and developed over the following decades into a central reference point for Roman provincial archaeology along the Danube Limes.

Yet this long history of research also had its downsides. Many early excavations still followed standards that are problematic from today’s perspective. Findings were often documented only briefly, and walls were secured or supplemented with modern materials after excavation. As a result, it was not always clear later on what was actually ancient and what originated from more recent restorations. Carnuntum was thus both at once: a scientific treasure of international significance and a challenge for heritage preservation.

A major milestone in raising public awareness of Carnuntum was the excavation of the amphitheater at the storage settlement, which began in 1886 under the auspices of the Carnuntum Association. For the first time, these monumental architectural remains were not only studied archaeologically but also preserved in a visible form, conserved, and made accessible to visitors. Later, the focus shifted primarily to the area near Petronell Castle: Between 1948 and 1958, an open-air museum was created there in the so-called Spaziergarten, designed to vividly convey Roman urban architecture.

For their time, these presentations were groundbreaking. They made Carnuntum visible, strengthened public interest, and contributed significantly to establishing the site’s reputation as an important Roman archaeological site. At the same time, however, the limitations of restoration practices at the time became apparent over time. Ancient walls were frequently secured with gray cement mortar, different construction phases often stood side by side without sufficient explanation, and floor levels or functional relationships remained difficult for the public to understand. After several decades, frost, moisture, and material stresses had severely damaged the restored walls. The ruins no longer appeared as a clearly legible section of an ancient city, but increasingly as a monument that was difficult to understand and at risk.

By the mid-1980s, the situation had come to a head. Many of the exposed ruins were severely damaged. Ancient lime mortar had been washed away, joints had frozen open, and modern restorations were detaching from the original structure. What had once been uncovered to reveal Carnuntum was now itself at risk. At the same time, the archaeological landscape was also coming under pressure from outside. Quarries, new residential areas, agricultural development, and looting threatened important excavation sites. Among the areas affected were the Pfaffenberg with its central Pannonian sanctuary, parts of the storage city, the legionary camp, as well as known and newly discovered settlement areas in Petronell-Carnuntum and Bad Deutsch-Altenburg.

Carnuntum thus stood at a turning point. Should the site continue to consist of isolated measures—an excavation here, a restoration there, a museum alongside it? Or was a long-term concept needed for the entire ancient urban landscape? The answer came in 1988: As part of the regionalization program, the Lower Austrian provincial government approved the “Carnuntum Project.” This laid the foundation for a new integration of research, historic preservation, public outreach, and regional development.

The 1988 resolution was far more than a mere tourism initiative. It aimed at a fundamental reorganization of the entire archaeological landscape. Carnuntum was to be not only preserved, but also researched, restored, developed for museum purposes, and presented to the public in an accessible manner—as Austria’s largest archaeological reserve. The project was planned in several phases. The focus was on three core zones: the museum district in Bad Deutsch-Altenburg with the Museum Carnuntinum, the legionary camp with the camp town and Amphitheater I, and the civilian city of Carnuntum surrounding the ancient city quarter near Petronell Castle. This three-part division was particularly important, as it made it clear that Carnuntum is not a single archaeological site, but a multi-layered Roman urban landscape comprising military, civilian, religious, economic, and ceremonial areas.

As early as 1988, an international symposium in Bad Deutsch-Altenburg provided important impetus for the future handling of the ruins. In the subsequent deliberations of the International Carnuntum Commission and the Building Advisory Board, a deliberately restrained concept emerged. Carnuntum was to become neither an “archaeological Disneyland” nor appear as a fully reconstructed ancient city. The goal was rather a scientifically grounded, verifiable, and restrained presentation—with restorations and reconstructions that explain without obscuring the ancient findings.

The laying of the cornerstone in 1989 marked the transition from planning to concrete implementation. In the years that followed, Carnuntum was gradually reorganized. The Museum Carnuntinum was restored and redesigned; further excavations and investigations took place in the areas of the military amphitheater and the civilian city; and ruins were renovated and re-presented. At the same time, important facilities for visitors were created, including an information center. The new approach was particularly evident in the so-called walking garden near Petronell Castle. There, older restorations were not simply carried over but critically reviewed. Problematic additions were examined, findings reevaluated, and structural relationships scientifically reconstructed.

In this way, historic preservation itself became part of the research. It was no longer just a matter of preserving Roman walls, but also of understanding how they had been excavated, restored, and presented over time. Carnuntum thus became reinterpretable not only as an ancient site, but also as the result of its own research history.

On June 9, 1996, the moment had finally arrived: the Carnuntum Archaeological Park was officially opened. After years of planning, research, and restoration, Carnuntum now had a solid foundation for modern visitor operations. Key areas had been renovated and made accessible, the infrastructure had been improved, new educational programs had been developed, and the museum’s focus had become clearer.

The opening also featured the exhibition “Horsemen Like Statues of Metal.” It made it clear that Carnuntum’s story cannot be told through ruins alone. Artifacts, images, inscriptions, sculptures, and everyday objects opened up new perspectives on the Roman city and its inhabitants. The new park thus connected several levels: the landscape, the excavated architectural remains, the museum, the history of research, and educational outreach.

Another important step was the founding of an operating company that same year. It established the organizational foundation for professionally managing visitor operations without losing sight of the scientific, conservation, and educational requirements. This was precisely a central feature of the project: The Carnuntum Archaeological Park was not created by separating research and tourism, but rather through an attempt to meaningfully combine both areas.

Since 2006, the reconstructions in Carnuntum have been gradually expanded. To this day, they define the character of the Archaeological Park and are the subject of ongoing, intense debate. Their purpose, however, extends far beyond mere illustration. They protect original findings, make archaeological research spatially tangible, and provide direct access to Roman architectural and everyday culture.

At the same time, reconstructions are always interpretations. They can give the impression that the past is clearly known and fully restorable. This is precisely why it is important in Carnuntum that they be understood as scientifically grounded, verifiable, and, as far as possible, reversible models. They do not present definitive truths, but rather plausible research scenarios. Their value lies in making complex findings understandable without obscuring their nature as interpretations.

Since its opening in 1996, the Carnuntum Archaeological Park has continued to evolve. New educational formats, guided tours, events, school programs, and thematic exhibitions have made Carnuntum a major cultural tourism destination in the region. At the same time, the scientific foundation has remained central. Modern survey methods, 3D documentation, and data-driven research approaches have significantly expanded our understanding of the ancient city over the past decades.

Today, this development can also be experienced digitally. The VR Experience in Carnuntum opens up new possibilities for conveying the site’s history in a vivid and immersive way. In the “Carnuntum Experience,” visitors embark on a virtual tour through Carnuntum during Roman times, gaining entirely new perspectives on the ancient metropolis.

The journey spans the centuries: from the city’s heyday to its gradual decline. Impressive 3D visualizations reveal how Carnuntum changed—as a city, as a landscape, and as an archaeological space of remembrance. Especially in this anniversary year, this makes it clear that the history of the Archaeological Park can be told not only chronologically but also spatially: as the transformation of a landscape, its research, and its presentation.

The 30th anniversary of the Carnuntum Archaeological Park is therefore more than just an occasion to look back. It demonstrates how closely archaeological research, historic preservation, museum education, and regional responsibility are intertwined. This is precisely where Carnuntum’s particular strength lies today: The ruins are not merely a preserved past, the reconstructions are not merely a backdrop, the museum is not merely a storage facility for finds, and the educational programs are not merely an additional tourist attraction. Together, they form a space in which archaeological research becomes visible, verifiable, and understandable. 

Carnuntum also demonstrates when reconstructions can be scientifically meaningful: when they do not replace research, but rather emerge from it. They are models, not certainties; interpretations, not copies; educational tools, not a substitute for antiquity. Their value lies in making complex findings legible while revealing how fragments, walls, artifacts, and traces come together to form a picture of past worlds.

Thirty years after its opening, the Carnuntum Archaeological Park thus represents a fundamental shift in how we approach archaeological heritage: away from isolated ruins, toward a researched, preserved, and interpreted urban landscape. The history of Carnuntum began long before 1996. But since that year, it has taken on a form in which research, preservation, and public engagement are permanently intertwined. This is precisely where the enduring significance of this project lies.
