Somewhat related, in 1943 German POWs built a scale model of the Mississippi River basin to use for modeling of flood control methods. (https://en.wikipedia.org/wiki/Mississippi_River_Basin_Model) It's not in great shape now, but it's still walkable. Efforts are periodically made to rehab it.

Models are such a great tool, artistically, culturally, and scientifically. Joe's NYC model really helps put the scale of the city into perspective.

Miniatures are fascinating.

There's also the San Francisco Bay Model, located in Sausalito, CA:

There's a model of Biblical Jerusalem at Temple Square in Salt Lake City, though I've no idea of its actual accuracy. This is located in the North Visitor's Centre: <https://www.myutahparks.com/things-to-do/attractions/temple-...>.

There's another such model at the Israel Museum in Jerusalem itself: <https://www.imj.org.il/en/wings/shrine-book/model-jerusalem-...>, and several others elsewhere in the world.

There are several models of ancient Rome, including appropriately one in Rome itself, the Plastico: <https://mymodernmet.com/scale-model-ancient-rome/>.

The Thorne Miniature Rooms at the Art Institute of Chicago are another delightful experience: <https://www.artic.edu/highlights/12/thorne-miniature-rooms>.
