Shanghai was the largest and most prosperous city in the Far East during the 1930s. In the past 20 years it has again become an attractive city for tourists from all over the world. The world once again had its eyes on the city when it hosted the 2010 World Expo, recording the greatest number of visitors in the event's history.
Shanghai is a fascinating mix of East and West. It has historic shikumen (石库门) houses that blend the styles of Chinese houses with European design flair, and it has one of the richest collections of Art Deco buildings in the world. As there were so many concessions (designated districts) to Western powers during the turn of the 20th century, in many places the city has a cosmopolitan feel. There is everything from classic Parisian style, to Tudor style buildings that give an English flair and 1930s buildings reminiscent of New York or Chicago. (Shanghai Wikitravel)
