# Oriental Pearl Tower

The Oriental Pearl Tower is a futurist TV tower in Lujiazui, Shanghai. Built from 1991 to 1994, the tower was the tallest structure in China until the completion of nearby World Financial Center in 2007. Its status as Shanghai's first AAAAA tourist attraction, the tower's unique architecture, height, and fifteen observation decks have made it a cultural icon of the city.

## Architecture

The top floor of the Oriental Pearl tower is at 351 metres (1,200 ft), which, combined with its 137 metres (450 ft) antenna, makes the tower 468 metres (1,500 ft) tall. The tower was the tallest freestanding structure in China and Asia from 1994 to 2007, but was later surpassed by Canton Tower in Guangzhou.

### Foundation

Located in Lujiazui on the banks of the Huangpu River, the Oriental Pearl Tower stands directly opposite of the Bund. Due to the area's soft soil, large concrete pillars were planted deep within the ground. Steel pipes and plates provided additional support. This technology was later used in nearby Jin Mao Tower.

### Spheres

Three large spherical platforms are connected by three pillars and an elevator in-between. According to its designers, the design, which reflects the culture of Shanghai, was inspired by "Pipa xing", a poem by Tang poet Bai Juyi. The spheres, which were constructed using an integral steel framework, are covered by concrete tiles and laminated red glass panes.

### Observation levels

The tower has fifteen observatory levels. Lower levels house amenities including a revolving restaurant, indoor roller coaster, and museums. Several levels, including the highest one, have panoramic glass floors. There is also a 20-room hotel, named the Space Hotel, between the two large spheres.
