The castle is very big, it has millions of corridors and halls, you never finish knowing everything. These are my seven favorite places in the castle, or outside the castle.
7. THE NORTH / EAST TOWER
Hogwarts have so many towers but this two are my favorites, the view in the top its crazy. We actually have the Divination classroom in the north tower. Get ready to go up million stairs.
6. THE LIBRARY.
There's not only one, not even two, Hogwarts had four library's (Rumors talk about a fifth library only with and for Dumbledore's book). My favorite one was the bigger of course, we used to spent most of our time there, not only studying, there's many books or famous novels that are very good. Did you know about a novel about Muggles life? Maybe a poetry book written for Beauxbaton's proffesors? and even they also have Guinness wizarding world record. I learn a lot of things in those books, magic is fantastic and never ends, you can actually find or create a new spell if you propose yourself to, well, i was very good at potions so i decided that i will work on some healthy potions the next time i arrive Hogwarts. Talking about medicine....
5. THE HOSPITAL
You're gonna ask, WHY? Lemme tell you that Miss Pomfrey are the best, people get used to go if they had headachache cause they know that Miss P will treat you like her own son. Thanks god i didn't get sick but one day i was around the castle and i found the hospital wing, miss Pomfrey invite me to go inside and she was the sweeties. I used to visit her anytime i got the chance and talk with her about magic medicine which is amazing and very difficult, its not only a spell and you are cure, this area is veery big and interesting. She had a lot of potions that help her to cure people, in here doesn't exist pills, that's muggle thing. Miss P introduce me to this world and she will like to know that i'll join this as soon as i get back there. "Oh how many Weasley's have been here and finally one get interested in my job. Fabiana, you will make amazing things." She said.
Secret about miss Pomfrey: She always prefer hufflepuff people and is her dreamiest house.
