Macau Historic District or Macau Historic Ancient District (formerly known as Macau Historic Architectural Complex) is composed of 22 buildings on the Macau Peninsula and eight adjacent forelands, with the core of the old urban district. At the 29th UNESCO World Heritage Committee meeting on July 15, 2005, it was officially listed in the World Heritage List, the 31st World Heritage Site in China. Macau's historic urban area is the oldest, largest, most complete and concentrated East-West style coexistence building complex in China, including the oldest church sites, monasteries, Christian cemeteries and Western-style batteries, the first Western-style theatre, modern lighthouse and Western-style university. As the first territory established by European countries in East Asia, Macau has witnessed over 400 years of history in which Chinese and Western cultures exchanged and coexisted. Most of the buildings in the urban area have the characteristics of Chinese and Western integration, and they are still well preserved or retained their original functions. Macau's historic city is the earliest, most and most important place in China to contact modern western artifacts and culture. It is also the first stop for modern western architecture to be introduced into China.
