“Does the car turn us into slaves?” This was the ominous question plastered across the Opinions page of Stavanger Aftenblad on June 1, 1968. In his op-ed piece, liberal politician Øyvind Bjorvatn complained about congestion and stress from increased car traffic, and argued that Stavanger should look towards Europe, “where more and more cities are dealing with the consequences of not being designed for car traffic.” 1 In Europe, Bjorvatn explained, neighborhoods were being closed off for cars and opened up for pedestrians, connecting the city through public transportation instead. Wasn’t it time for Stavanger to follow suit? Bjorvatn was not the only one who suggested looking towards Europe. A few years later, even the United States Environmental Protection Agency quoted the newly opened car-free zone of Vienna as models to follow. 2 Stretching across the two main shopping streets in front of the city´s historical St. Stephan’s cathedral, a fussgangerzone opened in Vienna on November 27, 1971 to performances by two of the city´s most experimental architecture groups, and, eventually, riots. 3 But more on that later.

Today, the notion of “walkable” cities has become a habitual and important term for urban planners and architects, and prioritizing pedestrians is seen as progressive and sustainable policy for urban development. In the time since Bjorvatn´s op-ed, Stavanger has introduced several car-free streets downtown, and more recently Pedersgata was converted into a one-way street in an effort to curb traffic. Stavanger even funds public and urban art festivals to activate urban spaces and to make the pedestrian experience of the city more spontaneous and pleasurable. While all of these practices might seem very in tune with contemporary interests and concerns, most of them actually have their origin in the 1960s. By the late 1960s, the idea of introducing car-free zones in downtown areas, for example, was becoming increasingly popular for many reasons. Urban centers were hollowing out due to suburbanization and the construction of shopping malls, gas was getting more expensive (the 1973 oil crisis would force prices to sky rocket and leave traffic at a standstill), roads and neighborhoods were getting more congested as more and more people could afford cars, and pollution was becoming a serious health risk for people living in certain areas and threatened entire cities like Los Angeles.
The idea that the city should be more than a functional center, but also provide stimulation and creative inspiration, was also an issue raised by many artists and architects of the time.
The spread of designated pedestrian zones was in part also due to the Austrian-born architect Victor Gruen. Hailed as the inventor of the modern shopping mall, Gruen, who was Jewish, had immigrated to New York right before the onset of the Second World War. In the United States he made a career designing indoor malls. Later he would also develop the idea of downtown pedestrian zones or so-called pedestrian malls. 4

The idea that the city should be more than a functional center, but also provide stimulation and creative inspiration, was also an issue raised by many artists and architects of the time. Bjorvatn´s suggestion that cars were also somehow detrimental to the human spirit (Did they turn us into slaves?) was in fact a sentiment shared by many European avant-garde artists and architects of the time. In the 1950s and 60s, the French Situationists drew psychogeographic maps to divide Paris into zones of emotional affect rather than activity or function. They also invented a tactical and spontaneous mode of wandering that they named dérive, intended as a way to experience the city outside of regular and “capitalist” patterns of use. 6

An Architecture of Play
Radical ideas like the ones outlined by the Situationists were also in play at the official opening of Vienna´s fussgangerzone. At the time, Vienna was a hub for several experimental architecture groups, and two of them, Haus Rucker-Co and Coop Himmelblau, had managed to get on the bill for the official opening. It is worth noting here that neither Haus Rucker-Co nor Coop Himmelblau should be understood as architects in any conventional sense of the term. While they had all met in architecture school, they were more interested in creating installations, inflatables, and performances than buildings. In fact, the ephemeral quality of their works seems to undermine the very idea of architecture as something “built” all together. Architecture, instead, was something to be moved around, performed, played with, and experienced. Architecture was something to make you feel.
The installations that the two architecture groups had devised for the opening day were all about feet (it was, after all, a fussgangerzone, literally meaning “foot” in German). Haus Rucker-Co had designed a “Walking School,” a sixty-meter long obstacle course that would allow participants to connect with their bipedal selves. “Send your foot back to school!” the project exclaimed, and invited pedestrians to experience “balance shifts” and “haptic walking” in order to train “a form of expansion of consciousness at the very bottom.” 7
- “Kunst,” Der Spiegel, December 13, 1971.
Coop Himmelblau also focused on feet in their project, City Soccer, or Stadtfussball. Four giant orange inflatable soccer balls were introduced to the streets, intended to engage city dwellers in spontaneous urban play by literally kicking the balls around on Kantnerstrasse. The balls were four meters tall and rose to the height of two-story structures as they were bounced around. With ten thousand visitors on opening day, the installations were a great success, even as the balls became increasingly dirtier throughout the day, as one local newspaper reported. 8

Architecture and Psychotropy
Walking School and City Soccer were not the first projects that Haus-Rucker Co and Coop Himmelblau had done that focused on play and sensuous experiences. In fact, a majority of their projects from this period were geared towards producing feelings of enjoyment and sociality in the user. Coop Himmelblau and Haus-Rucker-Co would include everything from tactile materials, music, and food to engage as many of the user´s senses as possible. On the occasion of the 1969 moon landing, for example, Haus-Rucker-Co devised a performance at Vienna´s historical Am Hof Square, which included a red heart-shaped inflatable, a three-meter long moon-shaped marzipan cake weighing 150 kilos, and a musical troupe performing Viennese folk songs. 10

But while all of Haus-Rucker-Co and Coop Himmelblau´s installations were intensely preoccupied with multisensory and bodily experiences, they were not all exclusively centered around play. Several of their projects actually focused on play´s opposite in terms of energy level: downtime, relaxation and rejuvenation. Coop Himmelblau´s Insider project, for example, consisted of a transportable and inflatable bed-pod where the user could retreat and enjoy soothing music accompanied by light projections. Haus-Rucker-Co´s installation Grüne Lunge (Green Lung) at the Kunsthalle Hamburg in 1973 consisted of an exterior platform with four transparent helmets where users could breathe air sourced from inside the Kunsthalle. Although Haus-Rucker-Co and Coop Himmelblau´s various installations from the late 1960s and early 1970s differed in some of their strategies and means, what characterized them all was that they seemed intent on manipulating the user´s mood by encouraging the release of dopamine or oxytocin, the hormones most commonly associated with feelings of pleasure, bonding, relaxation, and connection.
In his book Deep History and the Brain, historian Daniel Lord Smail proposes the term psychotropic mechanisms as a way to conceptualize social practices and behaviors that alter body-brain chemistry. Psychotropy basically refers to all the different things humans do in order to alter the mood of self or others, and are often geared towards increasing pleasure through the release of hormones such as oxytocin, dopamine, endorphins, or serotonin. 10

Even though Smail´s concept was not yet invented in the 1960s, Coop Himmelblau and Haus-Rucker Co would certainly have been very well aware of psychotropic effects. Countercultural experiments with LSD and other mind altering substances had also influenced the field of architecture: Austrian architect Hans Hollein had polemically suggested an “environmental pill” as a form of architecture, and several of Coop Himmelblau’s own installations had been designed with the specific intention of mimicking the effects of psychotropic drugs. 12

Feeling Tired?
Performed in the city, making strangers engage in silly, playful and social activities, Haus-Rucker-Co´s walking school and Coop Himmelblau´s giant balls seems like the perfect examples of psychotropic mechanisms. Because Coop Himmelblau and Haus-Rucker-Co reimagined architecture as specific urban and spatial installations that could engage the user in multiple ways, their installations also seemed better able to provoke emotional effects than a conventional building might have been able to. On the November day that their foot-centric installations were presented, however, experimental architecture was not the only environmental factor with a potentially psychotropic effect. Air pollution was also at a record high in Vienna. While air pollution is not exactly psychotropic, it can still have a very strong effect on humans. 13
- Psychotropic substances can, however, be found in air pollution. See Mark Wasuita, ”Ecstatic Air,” E-Flux Architecture, March 24, 2018, https://www.e-flux.com/architecture/superhumanity/179221/ecstatic-purification/.
Coop Himmeblau in particular would have been very aware of the negative effects of pollution on the human body and brain. In 1970 the group had conducted experiments in collaboration with the newly founded Institute of Environmental Health at the University of Vienna. As part of the experiments, Coop Himmelblau had designed a cylindrical inflatable structure described as a “pneumatic test chamber.” 14

The experiments were later featured on the national broadcasting channel in Austria as part of a series called Surviving in the Polluted Environment that addressed the increasing car use in the country. Towards the end of the 1960s, Austrians were beginning to experience the ramifications of two decades of increased urbanization and industrialization, as well as the influence of an emerging international environmental movement, and Surviving in the Polluted Environment was symptomatic of all of this. The opening logo was an ominous flickering image of a leafless tree with the word “Überleben” (Surviving) spelled out beneath, followed by a series of jump cuts of automobile exhaust pipes, conveying at once the country’s increased automobile ownership and its consequences for Austrian everyday life.
For the episode that featured Coop Himmelblau´s work, titled Pollution and Noise, a curious image materializes after the show´s intro: two disembodied arms emerge from off-screen to part the PVC curtains leading in to the Air Box, revealing a seated young man chewing gum and equipped with a headset and forehead electrodes. 16

Breach of the Peace
The car then, not only reduced people´s capacity and potential for play because they were dangerous and took up a lot of space, but also because the carbon monoxide they excreted produced the need for the opposite: rest. No wonder then, that Coop Himmelblau and Haus-Rucker-Co´s projects were always accompanied by projects to rejuvenate and relax the user. In fact, after the experiment on air pollution, Coop Himmelblau and the Institute for Environmental Health would collaborate on another experiment on how to create architectural environments intended for relaxation. 17

Returning to the fussgangerzone, however, which was not about relaxation but all about fun. Perhaps too much fun. Several of the local shop owners had been resistant to the idea of a pedestrian zone, especially the kind of experimental foot-festival that was proposed by Coop Himmelblau and Haus-Rucker-Co. "We have an audience that is used to having a certain peace, a certain atmosphere," the complaint went as business owners expressed concerns that the spectacle would attract families looking for “free” entertainment, displacing the more affluent middle class clientele usually found on Kantnerstrasse. 18

Perhaps the business owners were correct in assuming that Coop Himmelblau and Haus-Rucker-Co´s installations would be more than the Viennese could handle, perhaps their own bourgeois anxieties got in the way, or perhaps what happened next was exactly in line with Coop Himmelblau and Haus-Rucker-Co´s desire for an architecture that could rouse emotions. Either way, as the evening progressed, things began to get out of hand. Vandals attacked the giant soccer balls with knives; the foot school caused so much commotion and became so vandalized that it eventually had to be removed. People are unpredictable beings, feelings even more so. Especially when architecture tries to get the best of you.
