This seminar explores the evolution of historic preservation from a narrow focus on monumental properties to its broader, more complex, and more inclusive current purview. The course begins by learning about the history of the field of preservation through the understanding of its theoretical roots, definitions, professional practice, and the basics of material conservation. This introduction serves as a preamble to the second part of the course which focuses on the expanding role and potential future of historic preservation as it aligns its objectives with the principles of sustainability, social inclusion, and decolonization.
