The reconstruction of architectural heritage is a highly controversial topic, primarily due to the varying perspectives on its purpose and implications. While it serves as a tribute to demolished buildings, reflecting society’s attachment to their memories and values, this intention often ignites debates regarding authenticity and cultural representation. In 1994, the Nara Conference introduced the concept of cultural relativism, a key aspect of Cultural Anthropology, into the new international conservation doctrine. This approach recognized and respected diverse cultures, prompting a reevaluation of the foundational authenticity theories. This study takes Suzhou as a case example, selecting typical architectural heritage reconstruction cases from around 1980 to the present. It analyzes the historical processes of reconstruction cases in China and summarize the characteristics of conservation theory within the Chinese context. Furthermore, it explores the multiple cultural influences and inherent ethics associated with terms such as authenticity and integrity in the Chinese context, represented by Suzhou.
