Islamic Arts Biennale (2025) in Jeddah
The scenography designed by OMA (led by Iyad Alsaka and Kaveh Dabiri) for the second Islamic Arts Biennale (2025) in Jeddah is a fascinating masterclass in how to move away from rigid, "soulless" museum boxes. By leaning heavily into lightness, fluidity, and translucent textiles, the design creates an ethereal, atmospheric canvas that feels incredibly organic.
Rather than relying on solid, heavy walls to divide the massive 100,000-square-meter footprint under SOM’s iconic Western Hajj Terminal canopy, OMA opted for an "abstract architectural language" composed entirely of white fabric and dynamic light.
The layout is structured around seven distinct spatial experiences, with the fabric elements transforming to suit each theme:
AlBidayah ("The Beginning"): This section utilizes sweeping, curved translucent fabric walls to create intimate, fluid pathways. The soft geometry creates a reverent backdrop for the sacred artefacts, including the Kiswah (the cloth covering the Holy Kaaba), displayed outside Makkah in its entirety for the first time.
AlMadar ("The Orbit"): OMA punctuated this space with a literal forest of 37 abstract rectangular columns made of illuminated, translucent textiles. The effect is sculptural and rhythmic, replacing heavy stone pillars with pillars of pure light and woven texture.
AlMuqtani ("Homage"): Shifting from soft curves to a distinct graphic geometry, this area features a bowtie-shaped layout that divides the gallery into two symmetrical triangles, using beautifully pleated fabric walls and integrated vitrines to display diverse international collections.
The spatial progression functions less like a series of rooms and more like a fluid journey, where shadows, silhouettes, and changing light intensities dictate the transitions. It's an inspiring example of how architecture can step back to let cultural heritage breathe, using traditional material qualities—translucency, folds, and textiles—to evoke deeply contemplative spaces.
The true power of traditional Islamic art lies in how it completely redefines the relationship between structural form, surface ornament, and meaning. In Western art history, decoration is often treated as an after-thought—a secondary layer applied to a building or object. In the Islamic tradition, ornament is structural logic itself. It is a visual language designed to dissolve the weight of matter and transform a physical space into a contemplative, fluid experience.
This ethos manifests across three core disciplines, each relying on deep mathematical frameworks to evoke an ethereal, infinite sense of beauty.
1. Geometric Aniconism: The Mathematics of Infinite Growth
Because orthodox Islamic tradition avoids the depiction of sentient beings (aniconism) to prevent idolatry, artists turned to the pure, universal language of geometry. They took simple shapes—primarily the circle, square, and triangle—and used them as a structural matrix to create infinitely repeating tile networks, or girih.
[The Circle] ──► Basis for Unity & Balance
│
▼
[Square / Polygon] ──► Subdivision of Angles
│
▼
[Infinite Tessellation] ──► Star Polygons & Decagonal Tiles (Girih)
This is not mere decoration; it is a profound philosophical metaphor. A complex twelve-pointed star pattern starts from a single central point and radiates outward, mirroring the concept of Tawhid (the oneness and unity of God) and how the universe flows from a single source.
By the 15th century, craftsmen were executing quasi-crystalline mathematical patterns—structures that Western mathematicians didn't fully understand or prove theoretically until the 1970s. The walls don't feel solid; they ripple with an underlying order that seems to expand past the physical boundaries of the room.
2. The Weightless Topography: Muqarnas
If you look into the squinches, arches, or domes of classical Islamic architecture—like the Alhambra in Spain or the Shah Mosque in Isfahan—the corners don't look like load-bearing masonry. Instead, they dissolve into Muqarnas, a highly complex 3D honeycomb vaulting system.
The Optical Illusion of Muqarnas: By breaking down a solid, transitional corner into hundreds of tiny, interlocking corbeled cells, the architecture rejects rigid, heavy geometry. When light enters the dome, it catches the individual facets at different angles, creating an ethereal, weightless effect where stone or stucco appears to float like a stalactite cloud or a geometric crystalline mist.
3. Calligraphy as Spatial Architecture
In Islamic art, the word is not just read; it is experienced spatially. Calligraphy transforms static structural elements—beams, friezes, facades, and minarets—into fluid lyrical landscapes.
Artists masterfully select and adapt different scripts to match the physical scale and emotion of a space:
Kufic Script: Characterized by its bold, angular, and geometric lines. Because of its structural, architectural stability, it was traditionally carved into stone facades, brickwork, and early monumental structures.
Thuluth and Diwani Scripts: Known for their sweeping, cursive, and highly fluid vertical strokes. These scripts flow organically around the bases of domes and across tiled panels, bringing a sense of rhythmic, dancing movement to static plaster or ceramic tile.
When integrated into architecture, the text acts as a continuous ribbon of texture. Up close, a viewer reads the sacred poetry or prose; from a distance, the letters blend into a rich, abstract fabric that activates the entire surface of the building.
Whether expressed through the translucent textile pillars of OMA's modern biennial scenography or the deep granite carvings of ancient stone, Islamic art remains a timeless study in how to make the physical world feel entirely light, poetic, and unbound.
