Believe it or not, a hidden lost city lies beneath Sopron? Unveiling the underground secrets!

Sopron’s Underground Cellar Systems and Labyrinths

Although occasional rumors suggest that an entire lost city lies beneath Sopron, the reality is even more exciting: multiple levels of interconnected, historical cellar systems and tunnels extend beneath the city. These underground corridors and labyrinths are not just products of medieval or Baroque times – some sections date back to the Roman period, with walls and vaults reaching as far back as Roman times.

The Sopron underground cellar networks are remarkably diverse. They originate partly from the city’s winemaking traditions but also served strategic and defensive purposes. Most of these cellars are located in the city center and around the Várkerület (Castle District), but winding underground passages extend from the Sopronbánfalva area all the way to the historic city core.

During explorations, visitors can discover not only magnificent cellars but also old, blocked passages, forgotten staircases, arches, and dark, maze-like corridors. Some underground sites are still accessible via guided tours, making the Sopron underground secrets accessible and fascinating for visitors today!

Of particular importance is that over the centuries, some parts have been sealed off due to war events or deliberate closures. Since the 1950s, many cellars have been inaccessible to the public, but these hidden corridors still intrigue researchers, archaeologists, and adventurous visitors alike.

Scarbantia and Roman-age Sopron

The Roman predecessor of Sopron was known as Scarbantia, which was one of the most significant centers of winemaking and trade within the Province of Pannonia. The Romans designed the settlement with precise city planning, road networks, and extensive infrastructure. As early as the first century AD, significant underground defensive and storage facilities were developed—some of which are still discovered beneath the city today.

Notable are the Roman remains of baths and city walls. These remnants were incorporated into later medieval developments. The heart of Roman Scarbantia today is around Orsolya tér (Orsolya Square), where excavations have revealed mosaic floors, wall fragments, and substructures. The Roman-era relics here suggest, and confirm, that construction of underground infrastructure started around 1700–1800 years ago.

The remains of the Roman underground world are still studied by archaeologists today. Among the most exciting sites is the Scarbantia Archaeological Center at 4 Szeder Street, where temporary exhibitions and guided interactive tours offer deeper insights into Sopron’s ancient history. Here, visitors can see remains of a Roman well, public utilities, heating channels, and even parts of the original vaults!

The Mithras sanctuary is also noteworthy—a sacred site from ancient times buried underground. The Mithras temple and the Mithras Cave in Sopron are excellent examples of how spiritual and social activities took place underground, even during the Roman era.

Medieval Heritage and Defensive Constructions

Sopron’s landscape was definitively shaped during the Middle Ages, when it was built upon earlier Roman foundations with formidable defensive systems—city walls, bastions, and tunnels. During this period, the utilization of underground space became especially crucial—particularly in the 16th–17th centuries during Ottoman attacks, when many defense cellars and hiding places were constructed.

Sopron’s medieval city walls and their underground sections still offer intriguing opportunities for history enthusiasts. These sites include not only defense-related cellars but also parts of the medieval urban fabric—such as vaulted passages under Orsolya tér and underground sections along Várfalsétány.

Life in the medieval underground was vibrant: merchants, guilds, and winemakers used these systems for protection and economic activities for centuries. The Sopron cellar system has a unique structure: many of the cellars were interconnected, facilitating quick escapes or hidden freight transport.

The medieval layout of Sopron’s underground still echoes today, with ongoing archaeological research revealing new secrets about former city walls, gates, and even previously unknown passageways. The city’s history is thus preserved both above and below ground.

Archaeological Discoveries and Research Beneath Sopron

Sopron boasts a wealth of archaeological finds from various periods—Roman, medieval, and modern. During excavations, mosaics, wall paintings, rare pottery shards, wrought iron fittings, and various artifacts have been uncovered within the underground corridors, cellars, and chambers.

The Sopron Museum and several archaeological centers, such as the Scarbantia Archaeological Park, conduct ongoing excavations to make the hidden treasures beneath the city accessible to the public. The condition of the tunnels and chambers is monitored and preserved by the local government, Sopron Holding Zrt., and private researchers.

Many cellars have been restored and converted into exhibitions, offering guided tours. Often part of tourist attractions, these Sopron underground archaeological finds include remains of Roman baths, medieval fortifications, and Baroque vaulted cellars.

The greatest challenge in researching Sopron’s underground world lies in the fact that some tunnel sections have been sealed or filled in over the centuries. Nonetheless, new, previously unknown cellars, secret passages, and chambers are still discovered regularly, enriching the mosaic of Sopron’s history in Hungary.

Sopron Winery Tourism: Cellars and Experiences

You can’t truly get to know Sopron without exploring its wine cellars: the city has been a renowned wine-producing hub for centuries within the Carpathian Basin. The underground cellars and passageways preserve the local winemaking heritage, still shaping the city’s cultural and gastronomic identity today.

A key feature of the Sopron wine region is that many wine cellars extend directly beneath the city center. These have been used for aging local wines like Kékfrankos and others with techniques passed down through generations. The Sopron cellar tours remain among the most popular activities: multiple cellars offer organized, thematic visits, giving insight into both the world of wine and the stories of underground history.

One of the most famous is Pince Szalon in the city center, regularly hosting culinary events. The Sopron Wine Route (Sopron Borút) and local tourist attractions provide opportunities for underground tours combined with wine tastings, local cheeses, and authentic guided experiences.

Families interested in visiting can explore friendly, family-run wineries near Sopron, such as those in Sopronbánfalva or close to the Pálos Monastery. These locations offer memorable experiences beyond just tasting wine, including exploring the underground world—an activity suitable for all visitors, not only for wine enthusiasts.
