hidden passages
Secret building routes
Hidden passages are concealed corridors or routes within buildings, designed to be invisible to casual observers.
Old mansions and castles famously contain hidden passages behind bookcases or fireplaces, used historically for escape, concealment, or intrigue.
The term extends to secret routes through any space: The locals knew hidden passages through the marsh.
Figuratively, hidden passages may be obscure sections of text or unexplored paths through complex material.
