One of the most famous buildings in the Wizarding World is a school called Hogwarts. One of the reasons it is the most famous school is because Harry Potter went there.

Hogwarts is also one of the oldest buildings to still be running. It was founded around 990AD by four people: Godric Griffindor, Salazar Slytherin, Rowena Ravenclaw, and Helga Hufflepuff.

The first headmaster of Hogwarts was Nicholas De Mimsy Porpington who, instead of having a framed pictures of himself as all the past headmasters do, turned into a ghost, entertaining the students of Hogwarts.

Like said in Hogwarts Legacy and Hogwarts: A History, every brick in the castle has been made up of a point in history, like the Triwizard Tornament, which, due to certain safety points, has been stopped, and the dueling club. These can be dangerous, so the ministry of magical law enforcement, has been forbiddin.

The tension has also broken between Slytherin and Gryffindor, of which they had for so long. They realise it is wiser to be on speaking terms with each other.
