Qianmen (Front Gate) is the colloquial name for Zhengyangmen (meaning gate of the zenith Sun), a gate in Beijing's historic city wall. The gate is situated to the south of Tiananmen Square and once guarded the southern entry into the Inner City. Although much of Beijing's city walls were demolished, Qianmen remains an important geographical marker of the city. The city's central north-south axis passes through Zhengyangmen's main gate. photo take on: Apr 27, 2011
