Location from harry-potter-philosophers-stone by
The office of Albus Dumbledore, accessible by a spiral staircase behind a stone gargoyle, filled with whirring silver instruments, portraits of former headmasters, and the perch of Fawkes the phoenix.
Dumbledore's office is less a workspace than a repository of secrets. The candy-themed passwords — Sherbet Lemon is the one for this year — are Dumbledore's quiet joke: the most powerful wizard in the world protecting his sanctum with the name of a sweet. Every silver instrument does something Dumbledore never fully explains. The portraits of former Headmasters serve as advisors and informants. Harry visits here only briefly in Philosopher's Stone, but the office is already established as the place where critical truths are dispensed in careful doses. Dumbledore tells Harry about the Mirror of Erised here — that the happiest man in the world would see himself exactly as he is — and Harry files this away without yet understanding its weight.
A large circular room at the top of a moving spiral staircase, triggered by speaking a candy password to a stone gargoyle. The walls are covered with portraits of every previous Headmaster, all of whom can speak and pretend to be asleep. Delicate silver instruments whir and puff smoke on spindly tables. A vast claw-footed desk dominates the center. Behind it, the Sorting Hat sits on a shelf. A golden perch near the door holds Fawkes the phoenix.
