Where is the most indoors?

Suppose we define an indoors number
as the number of doorways that one must pass through to get from a given location to the outdoors. What location has the highest number?

For example, a closet in a bedroom of an apartment in a building with a common enclosed entryway would have an indoors number of 4.
I'm sure we're going to need some definitions to make this answerable. Let's define a location as any space where an average human can comfortably sit or stand, and a doorway as something that divides two spaces and has distinct open and closed states such that a human cannot pass when closed. It doesn't necessarily need to have a locking mechanism, just a distinct closed state. I don't want things like archways, porticoes, or turnstiles to count as doorways, but I'm not feeling rules-lawyer enough to try to come up with a formal definition that excludes them.
Only the shortest path from a location to the outside counts -- you can't detour through extra doorways if there's a more direct route available. And the path must have no cycles; you can't walk through the same doorway more than once.
I'm not quite sure how to define outside, and I'm hoping the common sense definition is not problematic. For example, an outdoor gate does count as a doorway; we'd consider the part inside the gate to not be fully outside, even if it's "outdoors".
Given those clumsy definitions, where on Earth is the most indoors? Is there a room in the bowels of the Pentagon or in a corner of an aircraft carrier that requires passing through 50 doors to get to?
