Saudi Arabia Pavilion: A Moon Boat to China

BOAT TO CHINA:Saudi Arabia Pavilion (CFP)

Instead of building an oil tanker for the pavilion as many might have expected, the oil-rich Saudi Arabia decided to instead build a moon-shaped boat "loaded with dreams and friendship."

The Saudi Arabia Pavilion is entitled the "Arabian City" and features the theme of "the Vitality of Life." Its primary purpose is to demonstrate how to realize "better city, better life" in the harsh desert climate.

Four types of cities are highlighted at exhibitions in the pavilion: the City of Energy, the City of Oasis, the Ancient City With Rich Cultural Heritage and the City of the Fast-growing Economy. The exhibitions demonstrate that water, petroleum and knowledge are the lifeblood of Saudi cities.

Date palm trees are planted both on the rooftop garden and the ground-floor garden of the pavilion, making the pavilion like an oasis in desert. For thousands of years, Saudi Arabians have harvested date palms as food.

A gigantic 3D IMAX screen and other hi-tech facilities are installed at the pavilion. Colorful art performances are staged there.
