I don't exactly understand the question but I'll give it my best shot. 1 external place was Hogwarts, this is where the battle of Hogwarts and the final confrontation of Voldemort and Harry Potter happened. Another is the burrow, Harry was accepted into the Weasley's home as one of their own and had his first real family. 12 Grimmauld place is another place of external experience. This is the home of Harry's godfather and close friend of his dad's. The ministry of magic is where all the wizarding leaders decide to make ignorant ideas and almost destroy the wizarding world. The last place in most of London when Harry, Ron, and Hermione went to search for Voldemort's Horcruxes. As for internal places, Harry Potter's first place was his heart. He had so many emotions and so much pain. Hemione"s brain got the golden trio out of many situations as well as put them into a few. Ron's loyalty and experience in the wizarding world got them far in life. Ron's family was also considered the lowest thing you could be aside from a mudblood so Ron's brain was clouded with negative thoughts of who he was for at least the first 3 books. Harry also grew up in a place where he was unwanted and his self- image was probably clouded with negativity which can overall affect his brain. Otherwise, Voldemort Horcruxes can count.
