To further clarify, there is no fortress "pile." Some people like to put them in a pile in their territory, but they do not go to a pile like artifacts.
Sometimes in t2 I'm forced to stack them due to room constraints, similar to how I stack redeemed souls (part of the card visible). I think that is fine; if your opponent can't tell what card it is from the part visible they're able to ask. Stacking them directly on top of each other (like artifacts) sounds like a bad idea.
Just checked with the rulebook, the collections of Fortresses, Sites, and Artifacts are all considered "piles"
Obligatory REG and rulebook are outdated post
What's with the hate? "Pile" doesn't mean directly stacked on top of each other. I can pile things so they are clearly visible to my opponent, and I usually announce things such as placing a fort in territory.
