If you want a page to show up on one of the Old Building pages, you should tag them accordingly:
- Oakland Historical Landmarks (for officially designated Oakland Historic Landmarks)
- National Register of Historic Places (for officially designated National Register places)
- demolished (obviously for something that has been.... demolished. not mutually exclusive from these others)
- historic place (not quite buildings, but still physical)
- not a landmark but should be (places OaklandWiki editors think are awesome but not yet recognized by The Establishment)
- historic districts (note plural) (blocks, neighborhoods, etc)
- natural landmark
- notable building (for things that aren't necessarily historic (or maybe they are) but are definitely, well, notable!)
for now, we are not using "landmark." if you have a building that doesn't fall into any of the other categories, and is old, "historic building" is okay for a default
