It is very unfortunate that so much of modern cultural heritage has been damaged or demolished in accordance with the demands of regional development. At a time when the courage to face the tragedy and pain of the past is needed, it is very meaningful to suggest a direction in which modern cultural heritage in Daejeon can be utilized as a tourist resource from a dark tourism perspective. This study both focuses on dark tourism, which combines history and education, and seeks a direction for the resourcezation of modern cultural heritage in the Daejeon area. To this end, the past and the present conditions of modern cultural heritage in Daejeon were examined, and the application method of the sites was presented from the aspect of dark tourism. Priority tasks should be the establishment of a concrete policy strategy on how to preserve and maintain the facilities and places of value as modern cultural heritage, the establishment of a detailed legal system, and ongoing administrative support. At the same time, another important thing that must be done is the establishment of a governance system in which local communities participate to promote the understanding of dark tourism and the revitalization of tourism, and the realization of the resourceization of dark tourism through the process of integrating various opinions. This research could provide an opportunity to induce the interest of tourists by linking it to the tourism industry through dark tourism, which has so far been of little interest.
