National Aquatics Center, one of the landmark buildings of Beijing 2008 Olympic Games, is located inside the Beijing Olympic Green. It is axially related to the National Stadium on the north part of Beijing Central Axis and reinforces the historical and cultural features of Beijing city.

The Beijing National Aquatics Center, also known as the National Aquatics Center, better known as the Water Cube, is an aquatics center that was built alongside Beijing National Stadium in the Olympic Green for the swimming competitions of the 2008 Summer Olympics.
The Aquatics Center hosted the Swimming, Diving and Synchronized Swimming events during the Olympics. Water Polo was originally planned to be hosted in the venue but was moved to the Ying Tung Natatorium.
Many people believe Water Cube to be the fastest Olympic pool in the world. It is 1 meter deeper than most Olympic pools. Up to a certain limit, beyond which swimmers will lose their sense of vision, deeper pools allow the waves to dissipate down to the bottom, leading to less water disturbance to the swimmers. The pool also has perforated gutters on both sides to absorb the waves.
With the popularity of the newly introduced faster Speedo LZR Racer swim suit, the Aquatics Center saw 25 world records broken in the Beijing Olympics.
