I don’t have that many particularly significant places on this planet. Those that would be are the “places” that are less about locations than they are about who happens to be there (i.e. “wherever my wife is”, “my close relative or friend’s current home”, and so on). These kinds of places can change as people move.
The more traditionally meaningful places have all fallen by the wayside. Significance has faded over time. The places themselves have fallen in to disrepair or become virtually unrecognizable. In perhaps my most personally significant case, they’ve disappeared completely.
