What "marks" the places in Lord of the Rings?

What kinds of symbolic stories might we tell about the place(s) or space(s) depicted above? How might the stories be "maps" or "tours", as de Certeau puts it?

Notice the various places depicted in the
Lord of the Rings movies (see here for more images):

The places tell us something about the kinds of people who live there. To some extent, they are interchangeable with the people. Witness how "out of place" Gimli the dwarf is when he is away from the mines. He is at home in the mines, and we can imagine their construction coming from folks like his.

Here's something to mull over - given what we've said, what kind of people would you think live at Hogwarts, the school in the Harry Potter movies?
