Docomomo is an acronym for the DOcumentation and COnservation of buildings, sites and neighborhoods of the MOdern MOvement. Docomomo promotes the study, interpretation and protection of the architecture, landscape and urban design of the Modern Movement. It promotes the exchange of knowledge about this important legacy which extends from the planned city and the iconic monument to the house next door. Docomomo is an international organization and Docomomo US is the working party of Docomomo in the United States. It is a 501(c)3 registered non-profit organization, a union of regional chapters that share its members’ knowledge of and enthusiasm for the Modern Movement, promote public interest in it through lectures and walking tours, and organize advocacy efforts to protect endangered sites and buildings. Committed to the principle that modern design merits the attention and preservation received by earlier periods, we maintain a continuous and constructive dialogue with national, state, and local preservation authorities and organizations as well as with building owners, developers, and designers in many disciplines. Our discussions with designing architects are based on the conviction that creative design and preservation go hand in hand. Designers are often consolidating, rehabilitating, and adding to the old; preservation architects are often devising creative ways to conserve it.
