Shanghai is one of the first cities in China that witnessed the skyscraper construction boom, the city had had the 420m Jin Mao Tower and 468m Oriental Pearl Tower built way back in 1990s, while the majority of the Chinese cities having the 100-meter-buildings as their tallest buildings.
In 2008, Shanghai World Financial Center got built, by then it was regarded as the tallest flat top building of the world and in 2015, the Shanghai Tower was completed in the city, which is the tallest in the country and the second tallest in the world.
It seems the the construction boom has temporarily come to an end as there's no serious supertall skyscrapers projects proposed in a long time.
As the skyscraper construction boom are taking places in other Chinese cities like a raging fire recent years, the number of supertall skyscrapers in these cities growing vigorously, Shanghai is no longer the city with most skyscrapers in China as it was in the past, many cities have already got more supertall skyscrapers built than Shanghai and still not slowing down on the pace.
Even so, Shanghai still possesses the tallest building of Eastern Asia, and the city features the world’s most majestic supertall complex that comprised of 3 supertall skyscrapers all exceeding 400 meters, in this respect no other cities is comparable to it currently.
Additionally, Shanghai is one of the minor cities that has four skyscraper based observation decks, this can be rarely found in other cities in the world.
There are 6 supertall skyscrapers in Shanghai as of 2016, tallest one is Shanghai Tower, which is second tallest building of the world. And the amount of 200-add-meter buildings reaches about 50.
