Recently there has been a greater demand for architectural conservators at archaeological sites. As archaeologists become increasingly aware of their ethical responsibility to conserve the architectural remains uncovered, the need for this type of expertise is acutely felt. The first part of this course will look at philosophical and ethical differences between structures which can be rehabilitated as architecture and those which will be stabilized as ruins, while reviewing the international organizations and charters which have been set up for this purpose. The second part of the course will deal with techniques of conservation, including site improvements, recording methods, reburial, consolidation, protection, sheltering, materials analyses and state of the art technology applicable to archaeological sites. Laboratory sessions, guest lectures, and field trips in the New York area will supplement lectures and student readings and projects.
