We develop and promote the conservation of immovable cultural heritage, including buildings, monuments, outdoor sculpture, and related sites. Architectural conservation is a discipline that addresses the unique conservation challenges of structures and sites. These works may be built on a vast scale; they are often exposed to weather and evolving climate factors; and projects often require research and cooperation with other diverse fields. We provide a forum for the exchange of information yielded from practice and research to further the profession and practice standards of architectural conservation.
