What is the name of the square next to the Bird's Nest?

The square on the west side of the Bird's Nest is the Celebration Square. The Celebration Square is paved with 995×495×150mm granite stones. LED lights are embedded between the stones. From south to north, huge "Beijing Welcomes You" and "Beijing Welcomes You" will be displayed. "One World, One Dream" and other Olympic slogans (visible from an aerial view), there are two musical dry fountains in the celebration square, which will be even more spectacular when they open.

Seven Star Plaza was formerly called "Seven Star Morgan Plaza". It was a famous building that caused great controversy in Beijing. The current building has been renamed "Pangu Grand View".

The blue square is the National Aquatics Center, commonly known as the "Water Cube" and "H2O3"
