The site where a body is interred is called a grave. Typically, a grave is excavated in the ground, and a stone bearing the deceased's details marks the spot.
There aren't many tangible reminders of a person's passing. You can visit their cemetery or hold onto a few of their items. It nearly feels like going to a loved one's house when you visit their grave.
It is simpler to feel their presence and recall your recollections of them. Even stories about their daily activities or successes are told by certain people.
Even after a loved one has died away, it still feels like they are sharing their life with them.
Such an interaction is very comforting and gives solace to people who are still mourning the loss. It is a tangible reminder that their loved one existed and will always be a part of their life in some ways.
