I recently decided to try creating a memory palace to memorize European countries, but I feel the environments I'm choosing are somewhat limited. I wanted to know two things: first, whether I can create multiple memory palaces—for instance, one for books, another for geography, and so on; and second, whether a hallway setting works well for a palace—like a museum gallery where I walk down the corridor and observe the things I want to memorize. I’d be grateful if anyone could answer this for me.
