The Los Angeles Conservancy

The Los Angeles Conservancy, the largest membership-based local historic preservation organization in the country, is dedicated to the recognition, preservation, and revitalization of the architectural and cultural heritage of greater Los Angeles. Established in 1978, the Conservancy grew out of the community-based effort to prevent demolition of the Los Angeles Central Library. The organization has grown to a membership of 7,000 households, including more than 400 volunteers. With a two-fold mission of advocacy and education, the Conservancy works to preserve existing architectural resources by developing preservation strategies and by raising public awareness of the value of those resources through tours, lectures, publications and programs.
