There is a lot of controversy these days with regard to the transport revolution. In addition to exciting pilot projects in some places, many cities and municipalities are still struggling to limit motorized private transport and attractively integrate alternative options into existing infrastructures. The list of alternative means of transport is not short. In addition to traditional public transport by bus and train or the use of bicycles, other means of transportation have been emerging for some time now. These are classified as micromobility.

This refers to transportation with lightweight, compact and individually usable devices. These can be designed with or without an electric motor. Micromobility vehicles are usually designed for short distances of just a few kilometers and travel at low speeds, usually under 25 kilometers per hour. The best-known example of micromobility is certainly the e-scooter, which experienced a real hype some time ago. Initially, a sharing provider in the e-scooter segment launched the first models on the market in Santa Monica/USA in the fall of 2017. From there, the concept quickly spread around the world. The scooters also arrived in Europe and it is now hard to imagine a city center without them. In Germany, a separate ordinance on the participation of small electric vehicles (with steering and handrails) in road traffic was even passed in June 2019 to regulate the use of scooters in urban traffic.

In addition to the much-discussed e-scooters, other means of transportation are also part of micromobility. These include Segways, e-light vehicles, hoverboards, monowheels, e-skateboards and classic skateboards. Thanks to their small size and flexibility, all of these devices offer significant advantages over cars, especially in urban environments. For example, they can be packed up quickly or parked almost anywhere and can also be used in zones that are closed to conventional car traffic. In addition to being user-friendly, micromobility could also actually contribute to a better urban climate. As the German Institute of Urban Affairs (Difu ) wrote in a 2021 report: “Micromobiles contribute to improving air quality, especially if they replace conventional car journeys.”

However, this statement reveals the dilemma of micromobility and a major point of criticism. This is because studies show that micromobility is not primarily intended to replace existing main modes of transportation. The e-scooter is not used instead of a car, but often in addition. For distances that would otherwise be covered on foot . This is not particularly dramatic for a skateboard without an electric motor. Micro-vehicles with an electric drive, on the other hand, are subject to criticism. This is because the environmental balance of electric mobility is controversial, as the mining of lithium on site, for example, can often hardly be guaranteed to be environmentally friendly and responsible.

Furthermore, the oversupply of scooters has not only done good things for the city’s infrastructure. In particular, e-scooters parked carelessly on the sidewalk can pose a danger to people with visual impairments, for example. Roland Stimpel, urban planner and chairman of the pedestrian protection association FUSS e.V., for example, emphasized in an interview with Deutschlandfunk that the scooters disrupt existing mobility rather than promoting it. Many cities are therefore trying to make adjustments. In some cases, there are already explicit scooter parking spaces. Or even zones in which parking and use are completely prohibited. For example in Paris. Following a citizen survey, a complete ban on e-scooters in the city center will come into force there from September this year.

So is micromobility more of a curse than a blessing? The debate cannot be resolved quite so simply. Because it is precisely where there are no other alternative means of transportation to the car that it unfolds its potential. For example, to link the surrounding countryside, the outskirts and the city center. Here, scooters, light electric vehicles or e-bikes can be used as feeder vehicles for the first or last mile in conjunction with public transport. Closing this gap in the public transport network makes the use of micromobility more attractive.

Another positive aspect is the shared ownership model promoted by micromobility. Sharing services run by a city council or a private institution prove that not every individual necessarily has to own a means of transportation. Rather, a shared fleet serves the community and everyone uses it freely as required. This is a major advantage over private cars, which spend most of their time unused. Such a model is also attractive from an economic point of view. This is because there is no need for the individual to take out insurance, carry out regular maintenance and buy fuel.

Forecasts predict that the micromobility market will continue to grow in the future. The market research company Grand View Research from the USA, for example, predicts an average annual growth rate of 7.6% in the e-scooter market between 2021 and 2028. If the technology continues to develop and cities manage to overcome logistical challenges in a smart way, micromobility could actually contribute to more sustainable mobility.

Rising high above the Thuringian countryside, Wartburg Castle is one of the most representative cultural monuments in Central Europe. Since its inscription on the UNESCO World Heritage List, it has been one of the most outstanding testimonies to European history. Architecture, political events and literary tradition intertwine here to create a multi-layered cultural narrative.

The history of Wartburg Castle begins in the 11th century, when it was founded as the residence of the Ludovingian landgraves and from then on shaped the political power in the region. Even in the High Middle Ages, the palace, enthroned on a steep limestone cliff, was considered a masterpiece of late Romanesque architecture, whose design and ornamentation make it one of the most important secular buildings north of the Alps. This architectural heritage is evidence of the feudal character of Central Europe and forms one of the foundations for the later recognition as a World Heritage Site.
Wartburg Castle’s role as a center of courtly culture and memory grows through literary traditions such as the so-called Singers’ War, which was passed down in Middle High German poetry. At the same time, historical figures such as St. Elisabeth of Thuringia, whose life and work are closely linked to the castle, are becoming firmly established in the culture of remembrance. Even if some legends were mythically exaggerated, they still reflect the early symbolic value of the place in the cultural imagination.

The architectural appearance of Wartburg Castle is the result of a long development that underwent a profound transformation, particularly in the 19th century. After centuries of changing use and partial decay, the emerging Romantic period initiated a comprehensive restoration that was based less on a historically accurate reconstruction than on an idealized image of the Middle Ages. Under this premise, the Elisabeth Bower and richly decorated interiors were created, which today form an integral part of the complex.
From an art historical perspective, this combination of original 12th century parts and historicist additions is ambivalent: on the one hand, the preserved Romanesque building elements document the civil architecture of its time; on the other hand, the 19th century additions reflect the monument preservation and historical myths of the time. It was precisely this mixture of archaeological and symbolic authenticity that was taken into account in the UNESCO nomination, with the term “authenticity” not only referring to material originality, but also including the ideas and meanings anchored in the collective consciousness.

Wartburg Castle is more than just a stone relic – it is a place of profound cultural connections. Martin Luther’s stay here during his exile from 1521 to 1522, when he wrote the German translation of the New Testament from Greek in the so-called “Junker Jörg” room, was particularly influential. This achievement in the history of language had far-reaching consequences for theology, education and the German literary language as a whole and had a lasting impact on the cultural significance of the castle.
In the 19th and early 20th centuries, Wartburg Castle also became a symbol of national identity and political integration. Events such as the Wartburg celebrations of the German student movement became part of the collective memory, as did literary and musical adaptations in works by Richard Wagner, which romanticized the image of the medieval castle courtyard. Wartburg Castle also remains a living point of reference in cultural memory as an inspirational place for artistic debate.
In 1999, the site was inscribed on the UNESCO World Heritage List on the basis of two criteria: Firstly, as an “outstanding monument of the era of feudalism in Central Europe” (criterion (iii)) and secondly, as a site “rich in cultural references”, particularly emphasizing its connection to the history of the Reformation and the German unification movement (criterion (vi)). These criteria reflect the exceptional universal value that Wartburg Castle has beyond the borders of Thuringia. The castle not only documents the architecture and living environment of high medieval feudalism, but also exemplifies the profound influence of historical events and cultural upheavals on European civilization. The UNESCO designation therefore not only recognizes the material substance of the complex, but above all its role as a place of remembrance that inspires generations of visitors to reflect and research. The integrative perception of architecture, history and cultural impact makes Wartburg Castle a unique medium for communicating the past and present.
At a time when cultural heritage is increasingly being discussed in a global context, Wartburg Castle highlights the importance of historical sites as mediators of identity, memory and transnational understanding. Its place on the World Heritage List helps to secure this significance in the long term and make it tangible for future generations.

“Security” in architecture means more than just barriers and alarm systems – there is much more to it than that. This issue sheds light on how buildings can provide protection – be it against the forces of nature, theft or social conflict. Your planners do not see security as a restriction, but as a design potential. In order to avoid repellent gestures, they often find security-relevant solutions in the building form. […]

“Security” in architecture means more than just barriers and alarm systems – there is much more to it than that. This issue sheds light on how buildings can provide protection – be it against the forces of nature, theft or social conflict. Your planners do not see security as a restriction, but as a design potential. To avoid repellent gestures, they often find security-related solutions in the building design.

Security – a word that is supposed to reassure and yet often has the opposite effect. We all long for it, but we also know that there is no such thing as absolute security. A building can protect against rain and cold, a city can be well planned – but can architecture really guarantee that we feel safe? Or does it only create an illusion? And in the end, isn’t the feeling of safety just as important as the safety itself?

The last year alone has shown us once again how fragile our built and lived environment is. Collapsing bridges, poorly maintained high-rise buildings and natural disasters that destroy entire neighborhoods. At the same time, fear of attacks in public spaces is growing, and in many cities measures are being taken to turn urban squares and buildings into high-security zones. But do we really need to turn our built reality into bastions of concrete and cameras in order to feel safe? Or is there a more intelligent answer to the question of protection?

Architecture cannot guarantee absolute security, but it can create trust. It can shape spaces that convey a sense of security without restricting freedom. Architecture has the unique potential to master precisely this balancing act. From fire and earthquake-proof school buildings to carefully considered designs for public spaces: Security architecture must not rely solely on control and barriers, but must enable trust and freedom. A clever choice of materials, for example, can preserve a feeling of openness without sacrificing protection. Ultimately, it must not be about sealing things off, but about proactive design.

Security must not become an aesthetic of mistrust. Walls, bars, barriers and confined spaces may minimize risks, but they also separate us from each other. All too often, they stifle life. The most popular place, both inside and out, is often where people meet, where light and transparency dominate, where architecture acts as a social bond and thus serves a greater purpose.

This issue is an invitation to rethink security. We show projects that prove that protection does not have to mean control, but trust. That architecture not only erects walls, but also builds bridges – between security and freedom, between control and openness. Because true security is not created by fear, but by clever (re)planning, by courageous design and by a society that does not close itself off, but proactively takes the helm. Enjoy reading!
