I've been wondering about this since I've heard a lot about the religious significance of places like Delphi but not much of the actual geographic Mount Olympus. After all, if Delphi was a big deal because it was the home of someone who could speak to the gods, wouldnt the place where the gods themselves lived be an even bigger deal? Were there any shrines, temples or something else of that nature?
