Lingnan architecture (), or Cantonese architecture, refers to the characteristic architectural style(s) of the Lingnan region – the Southern Chinese provinces of Guangdong and Guangxi. Usually, it is referring to the architecture associated with the Cantonese people, with other peoples in the area (such as the Hakka and the Teochew) having their own styles. This style began with the architecture of the ancient non-Han Nanyue people and absorbed certain architectural elements from the Tang Empire and Song Empire as the region sinicized in the later half of the first millennium AD. Modern day's Lingnan architecture is distinct from its counterparts in other Han Chinese regions because Cantonese people adapt their architecture to the geography of the region: the region has a subtropical climate, very unlike China's central plain (Zhongyuan). The set of building materials Cantonese have had access to also differs from that of other Han Chinese groups due to, for instance, difference in the tree species available. Overall, the classical Lingnan style, which is the best-known of Lingnan architecture, tends to favor pale colors such as green and white, avoid circular structures, adopt large numbers of relief carvings and sculptures, have many open structures like balconies and verandas, and be built using materials resistant to molds and moisture. The last two points are obviously related to the hot and humid subtropical climate of Lingnan. Chen Clan Ancestral Hall in Guangzhou is seen as a representative example of classical Lingnan architecture. The temple was built in late 19th century and served as an academy for Chan families in 72 counties of the Guangdong province. It comprises all sorts of folk architectural and decorative arts, and is famous for its "three carvings" (stone, wood and brick carvings), "three sculptures" (ceramic sculpture, clay sculpture and colorful sculpture) and "one cast" (cast iron). As a result, it is called the best of all the clan temples in the neighborhood.
