The architecture of the Czech Republic’s National Pavilion at Expo 2025 in Osaka is a manifesto of continuous development and the relentless energy of life. The design by Apropos Architects is a well-thought-out composition in which the main motif is the spiral – both in structural and symbolic form. It is the spiral, winding through 260 metres, that is central to the concept, introducing visitors to a journey whose movement reflects both the passage of time and personal and social development. Interestingly, the Polish Pavilion, which we described HERE, is also based on the spiral motif.
The central architectural motif of the pavilion is a 260-metre-long spiral path that wraps around the body of the building and leads visitors from the ground floor up to four storeys high. The journey ends on an observation deck 12 metres above the ground, offering views of the neighbouring pavilions and (through glass skylights) the interior of the auditorium. This dynamic form of movement – both physical and symbolic – reflects the cyclical nature of time, individual development and social growth. The architecture thus becomes a narrative and not just a backdrop for the exhibition.
Pavilion for body and spirit
Situated in the centre of the exhibition, the Czech Pavilion is the country’s showpiece. Its distinctive silhouette seems to expand upwards, as if defying the laws of gravity. The façade of transparent, artistic glass is not only a tribute to the rich tradition of Czech glassmaking, but also allows daylight to dynamically shape the interior atmosphere. The interior space changes with the movement of the sun, creating landscapes of light that enrich the perception of the exhibition.
Visitors traverse the pavilion on foot, engaging not only in physical movement but also in an artistic experience. A spiral path leads them around a central core – an auditorium with a diameter of 15.5 metres and a height of 12 metres, designed as a so-called ‘black box’ for cultural and educational events. With its flexible connection to the gallery, this space can function as a stand-alone auditorium or work harmoniously with the exhibition.
Two staircases – one for visitors, the other internal – ensure smooth movement and separation of exhibition and technical functions. Lifts and facilities for people with disabilities guarantee accessibility for all.
Construction and materials
The pavilion reaches a height of 16 metres and consists of 36 segments. On the lower levels, they form a circle, which on the upper floors flows smoothly into an ellipse, defining the final shape of the volume. The main load-bearing structure was created from cross-glued CLT timber panels of spruce, which shape both the core of the auditorium and the stairs and landings.
The ceilings and other structural elements were left exposed, emphasising the naturalness of the materials and the ecological design approach. The space in front of the pavilion is lined with a wooden terrace with seating areas.
A journey through art
An integral part of the architectural narrative is an exhibition of contemporary art created by Czech artists. The tour begins with a monumental crystal sculpture by Rony Plesl. Visitors then follow the drawing and painting of Jakub Matuška, known as Masker, which wraps around the inner spiral of the pavilion for more than 200 metres, serving as a metaphor for human endeavour and aspiration.
The experience is also enriched by a multimedia installation by the Lunchmeat Studio collective, which binds the space together with sound and light. Other artworks include a bronze sculpture by Alphonse Mucha and the glass installation ‘Herbarium’ created by Lasvit studio.
