Shanghai has become one of the world's most-populous cities (and one of the most economically important). From a skyline standpoint, the metropolis has it all. The famous Bund building is still characterized by the type of grand historic buildings that dominated the city during the 1920s, when it was a cultural and economic hub for all of East Asia. Look in another direction, however, and you will be confronted with a forest of modern skyscrapers.
The Bund can be seen from the Lujiazui area in the Pudong District, which itself has an impressively modern skyline that can be viewed from the water-front promenade on the Bund. A ferry service connects Pudong with the Bund, making it possible to grab a snapshot of both the modern and historic faces of Shanghai in one afternoon. To view the city from on high, the three observation decks on the top of the Shanghai World Financial Center can't be beat. The 100th floor deck is currently the tallest observation deck in the world, standing more than 1600 feet above the street.
