Sometimes after a venue/studio/whatever closes (and is usually later demolished), something up opens up where it once stood. There is currently no way to track this other than via annotations.

Example of a relationship:
Reunion Park is located on the former site of Reunion Arena
Reunion Arena once stood on the site of Reunion Park

I should note that this relationship is '''not''' intended for places whose names have changed. The latter case should still be tracked with aliases.
