Like The God That Crawls: for any corridor wall, but especially at corridor intersections: if behind the wall is nothing (stone), ~1-1.5m deep wall niche with high chance of having a stone plug jammed in to seal it. The stone plug will have a Fifthist symbol etched on it.
Opened with sledgehammer or crowbar to access good loot behind it, but opening it is loud.
