🏰 A History of Hogwarts 🏰

Over a thousand years of magic

The Founding (c. 990 A.D.)

The Four Founders

Around the year 990 A.D., four of the greatest witches and wizards of the age came together to create a school where young magical people could be trained safely, away from Muggle persecution. They built the castle in the Scottish Highlands, far from Muggle eyes.

🦁 Godric Gryffindor

From wild moor. Valued bravery, daring, nerve, and chivalry. His sword (goblin-made) became a Hogwarts treasure. Sorting Hat originally his hat. Best friend with Slytherin initially.

🦑 Helga Hufflepuff

From valley broad. Valued hard work, patience, loyalty, and fair play. Brought house-elves to work at Hogwarts, treating them kindly. Her cup became a Horcrux.

πŸ¦… Rowena Ravenclaw

From glen. Valued intelligence, learning, wisdom, and wit. Designed ever-changing floor plan of Hogwarts. Her diadem granted wisdom, was lost, became Horcrux.

🐍 Salazar Slytherin

From fen. Valued ambition, cunning, leadership, and resourcefulness. Built Chamber of Secrets. Left school after arguing with others about only teaching pure-bloods. His locket became Horcrux.
