Hogwarts

Hogwarts Castle is a large, seven-story high building supported by magic, with many towers and turrets and very deep dungeons, built in the late Early Middle Ages (c. 993) by a wizard architect and the four most celebrated wizards of the age: Godric Gryffindor, Helga Hufflepuff, Rowena Ravenclaw and Salazar Slytherin. The Castle houses Hogwarts School of Witchcraft and Wizardry, regarded as the finest wizarding school in the world.
Hogwarts is built in a valley area — surrounding mountains are part of the landscape — with the fairly large Black Lake to the south of the main building. The huge main oak front doors leading into the Entrance Hall face the west, and open up to sloping lawns. The deep Forbidden Forest extends around to the west of the Castle. There are also exterior greenhouses and vegetable patches on the school grounds.
Hogwarts is located in the Scottish Highlands, near the all-wizard village of Hogsmeade and "not far" from Dufftown, in Banffshire. Enjoy :)

Gryffindor. Founded by Godric Gryffindor. Its emblematic animal is the lion, and its colours are scarlet and gold. Minerva McGonagall is the most recent Head of House. Sir Nicholas de Mimsy-Porpington, also known as "Nearly Headless Nick" is the house ghost. The particular characteristics of students Sorted into Gryffindor are courage and chivalry. Gryffindor corresponds roughly to the element of fire, which may partly be the reason for its colours.

"You might belong in Gryffindor,
Where dwell the brave at heart,
Their daring, nerve and chivalry
Set Gryffindors apart"

Hufflepuff. Its founder was the medieval witch Helga Hufflepuff. The Head of Hufflepuff is Pomona Sprout. The Fat Friar is the House's patron ghost. Hufflepuff is the most inclusive among the four houses; valuing hard work, patience, loyalty, and fair play rather than a particular aptitude in its members. Its emblematic animal is the badger, and yellow and black are its colours. Hufflepuff corresponds roughly to the element of earth.

" You might belong in Hufflepuff,
Where they are just and loyal,
Those patient Hufflepuffs are true,
And unafraid of toil "

Ravenclaw. Founded by Rowena Ravenclaw. Members of this house are characterised by their wit, learning, and wisdom. Its house colours are blue and bronze, and its symbol is the eagle.[3] The house ghost, who in life was the daughter of the house's founder Rowena Ravenclaw, is the Grey Lady[4]. Many great wizards and witches have come from this house, including Filius Flitwick, Garrick Ollivander and Luna Lovegood. Ravenclaw roughly corresponds with the element of air.

" Or yet in wise old Ravenclaw,
If you've a ready mind,
Where those of wit and learning,
Will always find their kind. "

Slytherin. is traditionally home to students who exhibit such traits as cunning, resourcefulness and ambition. Its emblematic animal is the snake and its colours are green and silver. Founded by Salazar Slytherin, the house is composed mostly of pure-blood students, due to its founder's mistrust of Muggle-born witches and wizards. Slytherin house has a negative reputation, with many claiming that it is the source of most Dark Wizards in Britain, notably Tom Marvolo Riddle, a.k.a. Lord Voldemort, as well as many of his Death Eaters (followers). It has a traditional rivalry with Gryffindor. The great wizard Merlin was in Slytherin. Slytherin corresponds roughly with the element of water.

" Or perhaps in Slytherin,
You'll make your real friends,
Those cunning folk use any means,
To achieve their ends. "
