======Seventh Floor======
=====Location Information=====
  * **Type:** Floor of a [[school]]
  * **Location:** [[Hogwarts Castle]], Scotland
  * **Owner/Residents:** [[Hogwarts School of Witchcraft and Wizardry]]
  * **Key Features:** Contains the [[Gryffindor Tower]], the [[Room of Requirement]], the [[Divination classroom]], and the office of [[Professor Flitwick]].
=====Description and History=====
The seventh floor is one of the uppermost levels of [[Hogwarts Castle]], accessible via the [[Grand Staircase]]. It is a crucial area of the castle, housing the private quarters for an entire [[Hogwarts House|House]] as well as some of the school's most significant and secret locations.
The architecture of the floor includes long corridors, some of which are patrolled by [[Argus Filch]] and [[Mrs Norris]]. One notable corridor features a large [[tapestry]] depicting Barnabas the Barmy's foolish attempt to teach trolls ballet. Opposite this [[tapestry]] is a stretch of blank stone wall that conceals the entrance to the [[Room of Requirement]]. Another key area is found at the top of a narrow, spiral staircase, which leads to a small landing where a silver ladder provides access to the [[Divination classroom]] through a trapdoor. The [[East Wing]] of the seventh floor contains the office of [[Charms]] Master, [[Professor Flitwick]].
=====Role in the Story=====
The seventh floor serves as a backdrop for numerous pivotal events throughout the series, with its importance growing significantly in the later novels.
In //Harry Potter and the Philosopher's Stone//, it is primarily known as the location of the [[Gryffindor Tower]], accessed through the portrait of the [[Fat Lady]].
In //Harry Potter and the Prisoner of Azkaban//, the floor is the site of [[Sirius Black]]'s infiltration of [[Hogwarts]], where he slashes the [[Fat Lady]]'s portrait in an attempt to enter the [[Gryffindor Common Room]]. This book also introduces Professor [[Sybill Trelawney]]'s [[Divination classroom]].
The floor's role becomes central in //Harry Potter and the Order of the Phoenix// with the discovery of the [[Room of Requirement]]. Upon [[Dobby]]'s suggestion, [[Harry Potter]] uses the room as the secret training ground for [[Dumbledore's Army]]. The corridor outside the room is also where [[Harry]] shares his first kiss with [[Cho Chang]] under a sprig of [[mistletoe]].
In //Harry Potter and the Half-Blood Prince//, [[Harry]] becomes obsessed with the activities of [[Draco Malfoy]], who frequently disappears on the seventh floor. [[Draco]] is secretly using the [[Room of Requirement]] in its "Room of Hidden Things" configuration to repair a [[Vanishing Cabinet]], which he ultimately uses to smuggle [[Death Eaters]] into [[Hogwarts]].
During //Harry Potter and the Deathly Hallows//, the [[Room of Requirement]] on the seventh floor becomes a sanctuary for students resisting the regime of the [[Carrows]]. Led by [[Neville Longbottom]], the room provides food, shelter, and a secret passage to the [[Hog's Head Inn]] in [[Hogsmeade]]. During the [[Battle of Hogwarts]], [[Harry]] enters the room to find [[Ravenclaw's Diadem]], one of [[Lord Voldemort]]'s [[Horcrux|Horcruxes]]. The subsequent confrontation with [[Draco Malfoy]], [[Vincent Crabbe]], and [[Gregory Goyle]] results in [[Crabbe]] unleashing uncontrollable [[Fiendfyre]], which destroys the room and the [[diadem]].
=====Known Areas Within=====
  * **[[Gryffindor Tower]]**: The living quarters for [[Gryffindor]] students, including the [[Gryffindor Common Room]] and dormitories. The entrance is concealed behind the portrait of the [[Fat Lady]], who requires a password for entry.
  * **[[Room of Requirement]]**: A secret, unplottable room, also known as the Come and Go Room. It only appears when a person in great need walks past its location three times while concentrating on their need. Its various forms include a training hall, a storeroom for hidden objects, and a lavatory.
  * **[[Divination classroom]]**: The classroom of Professor [[Sybill Trelawney]], located at the very top of a spiral staircase. It is a circular, tower-like room filled with small tables, chintz armchairs, and the scent of perfume. Access is via a silver ladder and a trapdoor.
  * **Professor Flitwick's Office**: Located in the [[East Wing]] of the seventh floor. It is from this office's window that [[Professor Flitwick]] tearfully watched [[Fred Weasley|Fred]] and [[George Weasley]] fly away from [[Hogwarts]] on their brooms.
  * **Corridor with Barnabas the Barmy's Tapestry**: The corridor that houses the entrance to the [[Room of Requirement]].
=====Behind the Scenes=====
The film adaptations of the *Harry Potter* series feature various depictions of the seventh-floor corridors and the entrance to the [[Room of Requirement]]. While the core function remains the same, the specific architectural layout often differs from the descriptions in the novels for cinematic effect. (film)
