Three styles of architecture predominate in urban Beijing. First, the traditional architecture of imperial China, perhaps best exemplified by the massive Tian'anmen (Gate of Heavenly Peace), which remains the People's Republic of China's trademark edifice, the Forbidden City, the Imperial Ancestral Temple and the Temple of Heaven. Next there is what is sometimes referred to as the "Sino-Sov" style, built between the 1950s and the 1970s, with structures tending to be boxy and sometimes poorly constructed. Finally, there are much more modern architectural forms most noticeably in the area of the Beijing CBD and Beijing Financial Street.
Beijing of the early 21st century has witnessed tremendous growth of new building constructions, showing various modern styles from international designers. A mixture of both old and new styles of architecture can be seen at the 798 Art Zone, which mixes 1950s design with a blend of the new.
