Shanghai has always been one of the most developed and sophisticated cities in mainland China and in East Asia itself. Shanghai is a fascinating mix of East and West with houses that blend the styles of Chinese architecture with European design flair. The city is proud of having the richest collection of Art Deco buildings in the world. As there were so many concessions to Western powers during the turn of the 20th century, the city has a cosmopolitan feel. There is everything from classic Parisian style, to Tudor buildings and 1930s buildings reminiscent of Hollywood.
