=====Description and History=====
The Headmaster's office is a large, beautiful circular room located within a tower of [[Hogwarts Castle]]. Its walls are lined with portraits of all the previous Headmasters and Headmistresses of the school, who are known to sleep, snore, and offer counsel to the current Headmaster and each other. The room has several tall, arched windows that look out over the [[Hogwarts grounds]] towards the mountains.
The office is filled with numerous spindly-legged tables upon which sit a variety of "delicate silver instruments" that whir, puff smoke, and hum. The purpose of these devices is largely unknown, though [[Albus Dumbledore]] implied they tracked various magical phenomena. Key objects of immense importance are also stored here, including the [[Sorting Hat]], the [[Sword of Gryffindor]] (kept in a glass case), and Dumbledore's stone [[Pensieve]], which he kept in a dark cupboard. A golden perch beside the desk was home to [[Fawkes]], Dumbledore's [[phoenix]].
Access to the office is magically protected. The entrance is a single, polished oak door with a griffin-shaped knocker, located at the top of a concealed, moving spiral staircase. This staircase is hidden behind a large and rather ugly stone [[gargoyle]] in a corridor. The [[gargoyle]] will only spring aside to reveal the staircase when given the correct password. Under Dumbledore, these passwords were invariably the names of his favourite [[Muggle]] sweets, such as "//Sherbet Lemon//," "//Cockroach Cluster//," and "//Fizzing Whizzbee//." The office itself is magically sealed and will resist entry or full control by anyone it deems unworthy of the post, as demonstrated when [[Dolores Umbridge]] was unable to open Dumbledore's desk or remove the [[Sword of Gryffindor]] from its case.
Following Dumbledore's death, his portrait was magically added to the collection on the wall, appearing behind the Headmaster's desk.
=====Role in the Story=====
The Headmaster's office serves as a crucial setting for revelations, counsel, and pivotal plot developments throughout the series.
  * **Harry Potter and the Chamber of Secrets:** [[Harry Potter]]'s first visit is after crashing the [[Ford Anglia]]. Here, he meets [[Fawkes]] and discovers that the [[Sorting Hat]] can produce the [[Sword of Gryffindor]]. After defeating the [[basilisk]], Dumbledore uses the office to explain the nature of [[Tom Riddle]]'s diary and why Harry possesses some of [[Voldemort]]'s abilities.
  * **Harry Potter and the Goblet of Fire:** After his name emerges from the [[Goblet of Fire]], Harry is brought to the office. While waiting for Dumbledore, he discovers the [[Pensieve]] and views Dumbledore's memories of the trials of several [[Death Eaters]].
  * **Harry Potter and the Order of the Phoenix:** The office becomes a place of tension and distance between Harry and Dumbledore. It is later commandeered by [[Dolores Umbridge]], though she never gains full command of its magic. The story's climax unfolds here, as Dumbledore reveals the full contents of the [[prophecy]] to a grief-stricken Harry.
  * **Harry Potter and the Half-Blood Prince:** Harry and Dumbledore hold their private lessons in the office, using the [[Pensieve]] to explore [[Voldemort]]'s history and the secret of his [[Horcruxes]]. After Dumbledore's death, a large portrait of him appears here, and [[Minerva McGonagall]] uses the room as a base of operations.
  * **Harry Potter and the Deathly Hallows:** As Headmaster, [[Severus Snape]] uses the office, where he secretly communicates with Dumbledore's portrait to aid Harry's quest. In the aftermath of the [[Battle of Hogwarts]], Harry returns to the office to use the [[Pensieve]] to view Snape's memories. He then has a final, clarifying conversation with Dumbledore's portrait about the [[Deathly Hallows]] and his own destiny, before using the [[Elder Wand]] to repair his original holly and phoenix feather [[wand]].
=====Known Areas Within=====
  * **Gargoyle Corridor:** The entrance is guarded by a large stone [[gargoyle]] that demands a password. When the correct password is provided, the [[gargoyle]] moves aside, revealing a spiral staircase that moves upward like an escalator, carrying visitors to the office door.
  * **Main Office:** The primary circular room which houses the Headmaster's desk, the portraits of past Headmasters, and significant magical artifacts. This is where all meetings, lessons, and major revelations take place.
=====Behind the Scenes=====
  * In the film adaptations, the entrance to the office is a large, ornate griffin statue that unfurls its wings to reveal the staircase, rather than a stone gargoyle. The office itself is depicted as a vast, multi-level chamber combining a library and an observatory, far grander in scale than the single room described in the novels. (film)
  * J.K. Rowling has stated that Dumbledore's passwords being sweets is a reflection of his slightly eccentric and good-natured character.
  * The Pottermore website confirms that the office is one of the most secure locations in the castle and is enchanted to recognize the rightful Headmaster, sealing its secrets from usurpers like [[Dolores Umbridge]]. (Pottermore)
