Ministry of Magic

The ministry of magic is where many wizards and witches work to make sure that everything in the magical world goes smoothly.

Minister of Magic:

The minister of magic is in charge of the entire ministry of magic. They are the ones that look after everything, and are pretty much the head of that area of the wizarding area. The minister of magic from books 1 through 5 is Cornelius Fudge. He is fired, and Rufus Scrimgeour replaced him.

Entrance:

Most wizards and witches who work in the Ministry of Magic apparate there. However, there is a visitor’s entrance. You have to go to a certain phone booth, and press in the numbers 6-2-4-4-2 (m-a-g-i-c) in that order. It then takes you underground to the ministry of magic.
