The Oriental Pearl Tower (Chinese: 东方明珠塔; pinyin: Dōngfāng Míngzhūtǎ , Offical Name: 东方明珠电视塔) is a TV tower in Shanghai, China. The Oriental Pearl Tower is located at the tip of Lujiazui in the Pudong district, by the side of Huangpu River, opposite The Bund of Shanghai. It is modeled after the Fernsehturm.

[edit] Structural data

[edit] The Spheres in the tower

The tower features 11 spheres, big and small. The two biggest spheres, along the length of the tower, have diameters of 50 m for the lower and 45 m for the upper. They are linked by three columns, each 9 m in diameter. The highest sphere is 14 m in diameter.

The entire building is supported by three enormous and surprisingly strong columns that start underground.

[edit] Observation levels

The tower has three observatory levels. The highest (known as the Space Module) is at 350 m. The lower levels are at 263 m (Sightseeing Floor) and at 90 m (Space City). There is a revolving restaurant at the 267 m level. The project also contains exhibition facilities, restaurants and a shopping mall. There is also a 20 room hotel called the Space Hotel between the two large spheres.

[edit] Antenna spire

An antenna broadcasting TV and radio programs extends the construction by another 118 m.

[edit] Chinese symbolism in the design

The design of the building is based on a verse of the Tang Dynasty poem Pipa Song by Bai Juyi about the wonderful sprinkling sound of a pipa instrument, like pearls, big and small falling on a jade plate (大珠小珠落玉盘/大珠小珠落玉盤/dà zhū xiǎo zhū luò yù pán). The Oriental Pearl Tower consists of big and small balls, 11 in total. It is as if they are pearls falling down from the sky above on a jade plate, represented by the Huangpu river.

Seen from afar, the Yangpu bridge (杨浦大桥 Yángpǔ dàqiáo) and the Nanpu bridge (南浦大桥 Nánpǔ dàqiáo) seem like two Chinese dragons frolicking with the pearls of the Oriental Pearl tower.
