Book excerpt: One of the greatest challenges faced today by those responsible for ancient cultural sites is that of maintaining the delicate balance between conserving these fragile resources and making them available to increasing numbers of visitors. Tourism, unchecked development, and changing environmental conditions threaten significant historical sites throughout the world. These issues are among the topics dealt with in this book, which reports on the proceedings of an international conference on the conservation of classical sites in the Mediterranean region, organized by the Getty Conservation Institute and the J. Paul Getty Museum. The book includes chapters discussing management issues at three sites: Piazza Armerina, Sicily; Knossos, Crete; and Ephesus, Turkey. While visiting these sites, conference participants examined how issues raised at these locales can illuminate the challenges of management and conservation faced by complex heritage sites the world over. Additional chapters discuss such topics as the management of cultural sites, the reconstruction of ancient buildings, and ways of presenting and interpreting sites for today's visitors.
