Architectural Wonder—The "Breathing" Blue Bubble
The beauty of the Water Cube represents the ultimate expression of the intricate interplay between technology and art.
A Dreamlike Skin: The ETFE Membrane Structure
This constitutes the very soul of the Water Cube. Both the interior and exterior of the building are clad in layer upon layer of inflatable ETFE (ethylene-tetrafluoroethylene copolymer) cushions of varying shapes. Covering a total area of 300,000 square meters, this constitutes the world's largest membrane structure project—and the only large-scale public building to be completely enclosed using this material.
- From a Distance: Under the sunlight, this "skin" appears crystal-clear; shifting with the changing light of the sky and the movement of clouds, its hues transition from pale to deep blue, resembling a colossal, lustrous sapphire.
- Up Close: Upon closer inspection, these "bubbles" reveal themselves to be soft and elastic. Their surfaces are densely dotted with a pattern of silver spots that act like a precision lighting technician: they redirect light, blocking out harsh sunlight and excess heat while allowing soft, natural light to flood the interior of the venue—providing nearly 10 hours of natural illumination each day.
- As Night Falls: When the lights switch on, the Water Cube instantly transforms into a dreamlike Rubik's Cube of light and shadow. Illuminated by LED lighting, it appears at times as deep, tranquil blue as the ocean depths, and at others as vibrant and fluid as the Aurora Borealis. Photography Tip: The best time to take photos is around 6:00 PM in the evening, just as the lights are being switched on. By standing in the plaza on the south side of the venue, you can capture that classic, iconic shot featuring both the blue Water Cube and the red "Bird's Nest" National Stadium in a single frame.
A Square Form: The Philosophy of "Round Heaven, Square Earth"
The Water Cube features a precise square layout measuring 177 meters by 177 meters, standing in direct visual dialogue with the circular National Stadium (the "Bird's Nest") across the central axis. The pairing—one square, one round; one blue, one red; one soft, one rigid—not only creates a superb visual balance but also subtly echoes the ancient Chinese cosmology of "Round Heaven, Square Earth," embodying a profound dialogue between modern architecture and traditional culture.
2.2 Human-Centric Space: Flowing Jubilation and Glory
Step inside the Water Cube, and you will discover a vibrant, multi-layered interior space. The Olympic Competition Hall: Birthplace of Gold Medals
As the venue's central hub, the Competition Hall—measuring 116 meters long, 70 meters wide, and 30 meters high—encompasses a vast 8,120 square meters of space that instantly inspires awe. It features over 5,000 standard spectator seats, where the main pool’s azure waters gently ripple and the diving pool plunges into seemingly bottomless depths. From the stands, you can almost still hear the deafening cheers of 2008 and visualize the Five-Star Red Flag rising time and again. This is not merely a sanctuary for swimming enthusiasts, but the ultimate classroom for experiencing the true Olympic spirit.
Warm-up Pool & Multi-functional Zones
- Warm-up Pool: Constructed in strict accordance with international competition standards, this pool remains open to the public year-round. Bring your own swimwear and dive into the very waters where Olympic athletes once warmed up—a chance to experience what it feels like to be an "Olympian" yourself.
- "Water Droplet" Theater: A laser cinema spanning approximately 200 square meters with a seating capacity of 150. Utilizing state-of-the-art laser digital projection equipment, it screens films focused on science education and Olympic themes.
- Exploration Hall: Through a rich array of physical exhibits, this hall reveals to visitors the fascinating journey of how this architectural marvel rose from a mere concept to reality, and demonstrates how its three core design philosophies—"Green, High-Tech, and Humanistic"—were brought to life.
> Venue Insider Tips:
> The best vantage point for a panoramic shot is on Olympic Park Avenue, located on the venue's southern side; from here, you can capture both the Water Cube and the Bird's Nest in a single frame.
> Inside the venue, the prime spot for photography is the middle tier of the Competition Hall's spectator stands, offering a sweeping, unobstructed view of the entire swimming pool area.
> Keep an eye out for traces of the "Ice Cube" era; in specific designated zones, you can still view the curling lanes preserved in their original state.
