Areál Výzkumného ústavu cukrovarnického Střešovice Building

Welcome to Střešovice. Please, take a moment to settle in, adjust your headphones, and simply look around you. You are standing before the remarkable complex of the Výzkumný ústav cukrovarnický, the Sugar Research Institute. As you take in your first impression of the site, notice how the buildings seem to follow the natural flow of the land. This isn't a flat, rigid urban block; instead, the entire complex is thoughtfully integrated into the sloping terrain of this beautiful part of Prague. There is a certain quiet dignity to the atmosphere here, a sense of intellectual pursuit that has lingered in the air for over a century.

Let us step back in time to the beginning of the 1920s. Imagine the world just after the Great War, a time of immense change and a renewed drive for scientific progress. It was in 1920 that the construction of this research complex began. At the time, the sugar industry was a vital pillar of the economy, and there was a pressing need for a dedicated space where research and innovation could flourish. For two years, the site was a hive of activity, with workers and engineers shaping the landscape and raising the walls of what would become a center of excellence. By 1922, the original buildings were completed, marking the birth of a facility that would serve as a beacon of industrial science.

Now, I invite you to turn your attention to the architecture. As you look at the facades before you, you are actually witnessing a fascinating crossroads of design history. The man responsible for this vision was the architect Josef Záruba-Pfeffermann. He didn't stick to just one style; instead, he created a charming and sophisticated blend. If you look closely at the lines and proportions, you can see the influence of historicism, which looks back to the grandeur of the past to provide a sense of stability and prestige. But then, notice the shift toward something more rhythmic and stylized. This is the geometric Art Nouveau, a version of the style that moved away from flowing organic curves and toward cleaner, more structured patterns. And finally, you can sense the breath of the future in the early architectural modernism that permeates the site. It is this specific combination—the old, the decorative, and the functional—that gives the complex its unique and timeless character.

As you explore the area, keep in mind that you are not looking at a single monolith, but a carefully planned ensemble of seven different buildings. This includes the main research institute, which stands as the heart of the complex, and several accompanying villas. These villas weren't just residential spaces; they were part of a holistic environment where living and working were intertwined, fostering a community of scholars and researchers. If you can see the entrance to the main institute, imagine stepping into the vestibule. This space was designed to be the transition point between the outside world and the focused, silent world of the laboratory.

The history of this place is inextricably linked to the people who shaped it. Beyond the architectural genius of Josef Záruba-Pfeffermann, the name J. Bačkovský is also closely associated with the legacy of this site. These men were not just building offices and labs; they were creating a temple to science. They understood that the environment in which a scientist works can influence the quality of their discoveries. By placing the institute here in Střešovice, away from the chaotic noise of the city center but still within its reach, they ensured that the researchers had the peace and inspiration necessary for their complex work.

However, as the decades passed, the purpose of these buildings shifted, reflecting the broader political and scientific changes in Czechoslovakia. For nearly thirty years, the halls echoed with the study of sugar and chemistry. But in 1950, a significant transition occurred. The complex was acquired by the newly formed Central Institute of Physics. Think about the irony and the evolution of that change: a place built to study the sweetness of sugar became a place to study the fundamental laws of the universe and the mysteries of physics. The transition from chemistry to physics mirrored the global shift toward nuclear research and high-energy physics during the mid-century. The buildings remained the same, but the conversations inside changed from the molecular structure of sucrose to the behavior of atoms and particles.

There is something almost mysterious about this transition. When you look at the buildings now, you are seeing a shell that has housed two entirely different scientific worlds. It makes one wonder about the ghosts of ideas that still haunt these corridors—the forgotten formulas of the sugar researchers and the complex equations of the physicists. This layering of history is what makes the site so compelling. It is a physical record of how human curiosity evolves.

For a long time, the architectural value of this site was a quiet secret, known mostly to those who lived in the neighborhood or worked within its walls. But as our appreciation for early 20th-century modernism grew, so did the recognition of this complex. In 2010, the area was officially proposed for designation as a cultural monument. This proposal was a recognition that the work of Josef Záruba-Pfeffermann was not just functional, but an artistic contribution to the fabric of Prague. It acknowledged that the way these seven buildings interact with the slope of the hill and with each other is a masterclass in urban planning and aesthetic balance.

As you stand here now, I encourage you to take a slow walk around the perimeter. Notice how the light hits the facades and how the geometric details of the Art Nouveau elements emerge as you change your angle of view. Feel the slope of the ground beneath your feet and imagine the architects in 1920 sketching these plans, figuring out how to make the stone and mortar harmonize with the earth.

The Výzkumný ústav cukrovarnický is more than just a collection of old offices; it is a testament to a time when science, art, and architecture were seen as partners in the quest for progress. Whether it was the pursuit of a better sugar refining process or the exploration of the physical laws of nature, this site has always been about looking forward.

Thank you for joining me on this brief journey through the history of Střešovice. I invite you now to wander through the grounds at your own pace. Let the silence of the complex speak to you, and perhaps you will feel a spark of that same curiosity that drove the researchers who once walked these paths. Enjoy your exploration, and we will see you at the next stop.
