The SchUM sites in Speyer, Worms, and Mainz are among the most significant testaments to Jewish culture and history in Europe. They have been part of the UNESCO World Heritage List since 2021. As the cradle of Ashkenazi Judaism, they are among the most significant monuments of religious architecture and intellectual history in Europe. Their inclusion honors a culture that shaped the intellectual foundation of Jewish life in Central Europe and continues to have an impact to this day.

The name “SchUM” is derived from the Hebrew initial letters of the medieval city names Schpira (Speyer), Warmaisa (Worms), and Magenza (Mainz). As early as the High Middle Ages, these three cities formed an intellectual center of Jewish life north of the Alps. In the Early Middle Ages, a Jewish community emerged along the Rhine that would come to shape the entire Ashkenazi world. As early as the 10th and 11th centuries, these communities developed into intellectual and religious centers of European Jewry, whose influence extended far beyond the borders of the Holy Roman Empire. Rabbinic scholars such as Rashi and Rabbenu Gershom, the “Light of the Exile,” were active in these cities and laid the legal and theological foundations that continue to shape Jewish life to this day. Their responsa, commentaries, and synodal resolutions—the so-called Takkanot SchUM—defined norms for worship, marriage, and community that provided a binding framework for Ashkenazi Jewry for centuries.
The SchUM sites exemplify a cultural golden age that, despite repeated persecutions and destruction, remains visible to this day. Their inclusion on the UNESCO World Heritage List in 2021 recognizes their outstanding universal significance. Criteria (ii), (iii), and (vi) were particularly decisive in this regard: the exchange of human values, the unique testimony to a cultural tradition, and the direct connection to significant religious and spiritual developments.

Architecture and Symbolism of the SchUM Sites

Despite all the historical destruction, parts of the physical evidence of these flourishing communities have been preserved. Worms was home to one of Germany’s oldest synagogues, whose origins date back to the 11th century. The building was destroyed and rebuilt several times, most recently after World War II, with the reconstruction closely adhering to its historical form. The synagogue is not only a place of religious practice but also a symbol of continuity and reappropriation. The so-called Rashi Yeshiva (Jewish school) and the adjacent women’s school still convey an impression of the original spatial organization of medieval synagogue complexes. The women’s school is considered the first documented building of its kind in Europe and was constructed in 1212–13. It was separated from the men’s section by a wall fitted with listening slits.
Particularly impressive is the preserved mikveh in Speyer, a ritual immersion pool from the early 12th century that ranks among the oldest and best-preserved mikvaot north of the Alps. It was built in the Romanesque style and served as a model for many structures of this kind. Its location in an area with high groundwater levels, the meticulous stonemasonry, and its simple architectural dignity make it an outstanding testament to Jewish everyday culture. The ensemble is complemented by the Heiligen Sand in Worms, the oldest surviving Jewish cemetery in Europe, whose gravestones date back to the 11th century and represent a unique source for linguistic history, genealogy, and memorial culture.

Remembrance as a Mission

The UNESCO designation is not only a historical honor but also a mandate for preservation. Restoration efforts, archaeological research, and educational programs help make the SchUM sites, in all their complexity, accessible to future generations. The interfaith dialogue that emerges from their history is part of a modern understanding of cultural heritage that goes beyond mere preservation of monuments. As a visible symbol of Jewish life in Germany, the SchUM sites today stand for the rediscovery of cultural identity and a sense of responsibility toward a history that is deeply embedded in Europe’s collective memory. They serve as a reminder of times of intellectual flourishing and painful destruction—and of the enduring power of knowledge and faith, which managed to survive even under the most difficult conditions.
The significance of the SchUM sites lies not only in their architectural or historical substance, but in their ability to foster dialogue: between the past and the present, between religious communities and societal values. They symbolize the interplay of tradition and renewal, and an awareness of a history that has helped shape Europe. At a time when cultural heritage is increasingly viewed as a resource for understanding, the SchUM sites are more than monuments—they are living testimonies to a shared memory. Their STEINS, inscriptions, and stories call on us to take responsibility and to recognize Europe’s diversity as the foundation of the future.

The Department of Building and Environment and its partners will once again be presenting current projects and research results at the “Forum Building Science” symposium at Danube University – University for Continuing Education Krems in 2022. This year, the forum will take place for the first time in hybrid form (online and in the Audimax of the University for Continuing Education Krems). The focus is on.

In four blocks, the topics “Building and Climate”, “Heritage and Society”, “Heritage and Environment” and “Heritage and Economy” will be examined in different facets. Each thematic block consists of presentations and a concluding discussion. Current discussions, such as in the lecture “The European city under the consequences of climate change” by DDr. Dr.h.c. Pierre Laconte, Foundation for the Urban Environment, Brussels. Andreas Salvador Habsburg-Lothringen (The International Traditional Knowledge Institute Foundation (ITKI) Austria) and Univ.-Prof. Dr. sc. techn. Dipl. Arch. ETH Christian Hanus (Department of Building and Environment, University for Continuing Education Krems). About the “Center for Renewal Louka – Sustainable Future of Architectural Heritage” will speak Ing. arch. Iveta Ludvíková, city architect of the city of Znojmo (CZ), Ing. arch. Vratislav Zíka, Faculty of Architecture, Brno University of Technology (CZ) and Darya Haroshka, MSc (Center for Architectural Heritage, University of Continuing Education Krems).

The “Accademia Vicino” in Accumoli

The focus is also on the “Accademia Vicino”, an initiative of Danube University Krems, which, together with other European research institutions in Accumoli with the “Scuola di Ricostruzione”, is dedicated to topics such as the earthquake-proof reconstruction of historic buildings. This also includes the revitalization of the social, cultural and economic structures in Accumoli.

The event is free of charge, but registration is required for organizational reasons. You can find the complete program here.

Since its foundation, the Department of Art, Education and Architecture has been characterized by its focus on current socially relevant issues, combining expertise in ecology, economics and culture to develop sustainable architecture and living spaces “The development of new paradigms in the entire field of building culture is at the heart of our research activities. In doing so, we focus less on predetermined solutions and more on situation-specific goals,” explains Univ.-Prof. Dipl. Arch. ETH Dr. Christian Hanus. Special areas of expertise include daylight planning, the energy efficiency of old buildings, the protection of cultural assets in accordance with the 1954 Hague Convention and the valuation of listed buildings.

Reading tip: Since 2016, the Faculty of Education, Art and Architecture at Danube University Krems has been supporting the region around Accumoli, which was hit hard by earthquakes, with teaching and research projects at the “School of Reconstruction”. In addition to the structural reconstruction, the aim of the efforts is also the cultural, social and economic revitalization of the central Italian municipality. With this in mind, the international orchestra academy “Accademia Vicino” was launched in Accumoli, including a series of concerts with conductor Johannes Wildner. Read more here.

The 30 km/h zone in Germany

The 30 km/h zone in urban areas could become a reality. Which roads are affected? How can you suggest roads yourself? What are the advantages and disadvantages of the 30 km/h zone? What is “forever <30”? Everything you need to know.

Seven cities want 30 km/h zones throughout the city

Since 2021, seven German cities have been campaigning for 30 km/h zones throughout the city. Aachen, Augsburg, Freiburg im Breisgau, Hanover, Leipzig, Münster and Ulm want to reduce the speed limit across a large area as part of a pilot project. Speeds of 50 km/h will then only be permitted on a few main roads. The cities want to use this initiative to bring about a change in the law. The initiative is supported by Agora Verkehrswende and the German Association of Cities.

“After the federal elections, we want to create a regulation in the short term that will enable local authorities to decide flexibly and objectively on a speed level that is appropriate and compatible with the city in the entire inner-city road network.” Back in July 2021, the initiative declared its intention to bring about an amendment to the Road Traffic Act. This would allow cities to set a 30 km/h speed limit on a large scale in the future.

The seven pioneering cities emphasize that this is not an initiative against motorists. Rather, the extended 30 km/h zones are intended to benefit the residents of the respective municipalities. “The efficiency of traffic is not restricted by a 30 km/h speed limit, but the quality of life is noticeably increased,” says a statement from the cities.

The advantages of 30 km/h zones

There have long been 30 km/h zones in German city centers and near schools and kindergartens. These are intended to make the roads safer for pedestrians and cyclists. According to the World Health Organization (WHO), 1.3 million people worldwide die in road traffic accidents every year. This number can be significantly reduced by slowing down. And drivers are also safer when driving at 30 km/h.

The zones with lower speeds also have the advantage of reducing traffic noise and air pollution. In cities such as Frankfurt am Main, driving bans have already been discussed in order to reduce high levels of nitrogen pollution. Emissions can already be significantly reduced at 30 km/h.

A few steps have already been taken abroad: since the end of September 2021, a 30 km/h speed limit has been in force on the majority of Parisian roads. 59% of Parisians support this speed limit. In Spain, around 80 percent of all urban areas are 30 km/h zones. Here, the maximum speed depends on the number of lanes. On single-lane roads without markings in the middle, only 20 km/h is permitted.

The idea behind 30 km/h zones

30 km/h zones are supported by many organizations, but also by residents and environmentalists. In Germany, it is currently still necessary to justify a deviation from the usual 50 km/h in the city. It is therefore usually only possible to reduce the speed in residential areas and for child and noise protection. Many 30 km/h zones are short or only apply at certain times.

According to Deutsche Umwelthilfe, this is not sufficient to achieve the positive effects of these zones on traffic flow, mobility behavior, environmental impact and accident figures. The organization is therefore calling for a 30 km/h speed limit in built-up areas throughout Germany.

Umwelthilfe points to the positive figures from other European cities, where up to 70 percent fewer accidents per year have been recorded since the introduction of 30 km/h zones. The World Health Organization also advocates a 30 km/h speed limit in all cities and villages around the world in order to protect human lives.

With the “Always under 30” initiative, Deutsche Umwelthilfe offers materials and support for local authorities that want to introduce 30 km/h zones. 140 municipalities in Germany have already joined forces to form an alliance. Together, they are calling on Federal Transport Minister Wissing to give them more room for maneuver. This would allow local authorities to impose a 30 km/h speed limit on main roads. So far, however, there have been no changes to the road traffic regulations regarding 30 km/h zones.

Background: Under 30 since 1979

30 km/h zones are used in Germany to calm traffic. According to “Vision Zero”, people are significantly less likely to die in a collision at 30 km/h than at 50 km/h. The aim is to reduce the number of traffic fatalities in Germany to zero.

The first traffic-calmed zone in Germany was created in Hamburg’s Lindenallee in 1979. In this 30 km/h zone, sidewalks and roads were also combined, parking zones were set up and greened swerves were built. The nearby city center of Buxtehude became the first major 30 km/h zone in Germany in 1983. Other cities such as Munich and Cologne followed suit.

Today, Freiburg is one of the most active cities in the field of road safety and environmental friendliness. With a pilot project, the city wants to demonstrate how 30 km/h could work throughout the city. In the spirit of the mobility transition, Freiburg is also encouraging other cities to join the initiative of Agora and the German Association of Cities.
