Space Needle
스페이스 니들
The Space Needle is an observation tower in Seattle, a city in the state of Washington in the north-west United States. It was built for the 1962 World's Fair, which had a space-age theme and drew more than 2.3 million visitors. With its slim legs and a disc on top that looks like a flying saucer, it quickly became the symbol of the city.

Quick answers
Where is Space Needle?
Space Needle is in Seattle, USA, United States.
When was Space Needle built?
Space Needle was built in 1962.
How tall is Space Needle?
Space Needle is about 184 m tall.
A futuristic observation tower built for the 1962 World's Fair, Seattle's signature landmark.
The tower is 184 metres tall and 42 metres wide at its widest point. When it opened it was the tallest building west of the Mississippi River in the United States. Today taller skyscrapers stand nearby, but the Needle is still Seattle's best-known landmark, and in 1999 the city officially named it a historic landmark. It is privately owned and is not used for broadcasting.
How it was designed and built
The design mixed ideas from several people. Edward Carlson, an organiser of the fair, sketched a giant balloon tied to the ground on a napkin after seeing a TV tower with a restaurant in Germany. The architect John Graham added the idea of a flying saucer on top, and Victor Steinbrueck gave the tower its narrow-waisted, hourglass shape standing on three legs. Building started in April 1961, the basic tower was finished just eight months later in December, and it opened with the fair on 21 April 1962.
Built to stay standing
Seattle has strong storms and earthquakes, so the Needle was made extra tough. It weighs about 8,660 tonnes, and its underground foundation weighs about as much as the whole tower above it, so its centre of gravity is only about 1.5 metres above the ground. That keeps it steady, a bit like a weighted toy that always stands back up. Engineers designed it to survive winds of up to 320 kilometres per hour, double what the 1962 building rules required, and very large earthquakes. During a strong earthquake in 2001 the tower shook enough to slosh water out of the toilets, but it was not seriously damaged.
Visiting today
Elevators carry visitors to the observation deck, 160 metres above the ground, in about 41 seconds. From there you can see downtown Seattle, Puget Sound and its islands, and on clear days the snowy volcano Mount Rainier. A big renovation finished in 2018 added floor-to-ceiling glass walls and the Loupe, a level with a slowly turning glass floor that lets you look straight down. On special days a strong beam of light, called the Legacy Light, shines up into the sky from the top.
