“Dark tourism,” which is one of the alternative tourism types, is travels to areas where collective or individual deaths occur and to places like monuments. The construction of monuments and memorial parks in memory of those who were lost in the war, the conversion of prisons into museums, the influx of visitors to the areas assumed to have witnessed various religious and cultural events, make these areas a "memory space" and appear as phenomena that support the concept of "dark tourism." Memory spaces are also important recreation and tourism areas in terms of landscape architecture. In this context, the study aims to evaluate the situation in Turkey in terms of landscape architecture by examining the phenomenon of memory space, which is a new concept, with examples. In the study; from the perspective of landscape architecture, the concepts of memory spaces, spatial memory and dark tourism are explained, the relationship between spatial memory and dark tourism has been examined, and the phenomenon of dark tourism as the expression and carrier of collective memory has been emphasized. Tourism areas within this scope have been examined under the categories of natural disasters, important people, accidents, social event and war. In the study, the examples in various parts of the world and in Turkey were examined and the potential of Turkey in this context was evaluated. As a result, it has been determined that Turkey has an important tourism potential in this sense. In addition, in order to evaluate this potential correctly, suggestions have been developed with the focus of designers and administrators.
