Dark tourism has been defined as tourism involving travel to places historically associated with death and tragedy. More recently, it was suggested that the concept should also include reasons tourists visit that site, since the site's attributes alone may not make a visitor a "dark tourist". Thanatourism, derived from the ancient Greek word thanatos for the personification of death, refers more specifically to peaceful death; it is used in fewer contexts than the terms dark tourism and grief tourism. The main attraction to dark locations is their historical value rather than their associations with death and suffering.
