Hogwarts Castle

"*The castle is a stronghold of ancient magic.*"
— Albus Dumbledore regarding the ancient castle

**Hogwarts Castle** was a large, seven-storey high building supported by magic, with a hundred and forty two staircases throughout its many towers and turrets and very deep dungeons. The castle was 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 was the main building of Hogwarts School of Witchcraft and Wizardry, regarded as the finest wizarding school in the world.

Hogwarts was built in a valley area - surrounding mountains were part of the landscape - with the fairly large Great Lake to the south of the main building. The huge main oak front doors that led into the Entrance Hall faced west, and opened up to sloping lawns. The deep Forbidden Forest extended around to the west of the castle. There were also exterior greenhouses and vegetable patches on the school grounds.

Hogwarts was loctaed in the Scottish Highlands, near the all-wizard village of Hogsmeade and "not far" from Dufftown, in Moray, and Achintee, in Lochaber.

It was the setting of the final battle of the Second Wizarding War, the Battle of Hogwarts, which resulted in the deaths of several wizards who fought in the defence of the castle, including Remus Lupin, Nymphadora Tonks, Fred Weasley, Colin Creevey, Lavender Brown, and Severus Snape. The castle was badly damaged in the battle, but ultimately the Order of the Phoenix won when Harry Potter defeated his nemesis, Lord Voldemort, in the Great Hall.

Due to its extremely advanced age and the sheer amount of magic present in or around it, the castle was implied to have developed some form of sentience or awareness, such as when it sealed the Headmaster's Tower against Dolores Umbridge in 1996, and the various trick steps and false doors.

## Magic

The castle was supported by magic (unable to be maintained or constructed by any other means), a good example being the moving staircases, a feature contributed by one of the four Hogwarts founders, Rowena Ravenclaw.

Hogwarts was also protected by numerous ancient spells, such as the Anti-Disapparition Jinx; this could, however, be overridden by the Headmaster (and Dumbledore's phoenix, Fawkes) when necessary. It was also unplottable and bewitched so that, if Muggles approached the castle, all they would see would be a moulding ruin with a sign warning them to keep out and that it was unsafe. The protective magic over Hogwarts was not only strong enough to apparently resist the dispelling effects of the Taboo, but also to repel even talented Dark Wizards.

Rubeus Hagrid claimed that Hogwarts was the safest place there was, even more so than Gringotts Wizarding Bank, a reason why the Philosopher's Stone was sent to the castle for protection. After the Ministry finally admitted that Lord Voldemort had returned in 1996, the castle's defences were further increased, much of them were cast by Albus Dumbledore himself, such as gates being locked with spells that can only be undone by teachers, and spells to prevent entrance via broomstick. All of the secret passageways that were previously allegedly unknown were given more protection. Additionally, with members of the Order of the Phoenix and Aurors placed as guards, and Caretaker Argus Filch checking all incoming and outgoing students for dangerous materials, intrusion seemed completely impossible.

However, Draco Malfoy utilised a pair of Vanishing Cabinets as a passageway, which none of the castle's defences could negate, to allow Death Eaters into the castle. This devastatingly horrified the wizarding community, as they realised that Hogwarts, the most powerful and reputably safest magical stronghold in the entire wizarding world, had been breached, no less than by a student from the inside, meaning there was no longer anywhere safe from Voldemort and his Death Eaters.

As a result of all the magic that occurred on the premise (both from learning students, magical artefacts therein and the enchantments cast over the building itself) a magical atmosphere pervaded the entire structure, causing any technology that was no adapted to run off of it to fail. This was presumably why candles and lanterns were used for light. Mechanical things like watches seemed to do alright, as Colin Creevey's traditional Muggle camera seemed to have worked until it was destroyed by the Basilisk's eyes. (Colin mentioned that another student told him that he could develop the pictures in a potion so that they moved. One of his pictures showed Harry trying to escape a picture of him and Gilderoy Lockhart).

## Below the Ground Floor

### Chamber of Secrets

*Main article: Chamber of Secrets*

"*He was standing at the end of a long, dimly lit chamber. Towering stone pillars entwined with more serpents, rose to a ceiling lost in darkness, casting long, black shadows through the odd, greenish gloom that filled the place.*"
— Harry exploring the Chamber

The Chamber of Secrets was allegedly created deep under the dungeons of Hogwarts Castle during the Medieval times by Salazar Slytherin, who disagreed with the other Hogwarts Founders on the merits of blood purity. The Chamber of Secrets was home to an ancient Basilisk, which was intended to be used to purge the school of Muggleborn students.

The entrance could be found in Moaning Myrtle's bathroom on the second floor. In order to gain entrance one had to say "open" in Parseltongue, and a sink would open into a slide. While falling down the large, dark pipe, one could see hundreds of other pipes leading off. At the end of the pipe, one was launched into a damp, stone chamber. This room was stated to me "*miles beneath the school*" and under the Lake. This was where Tom Marvolo Riddle used his ability to speak Parseltongue and attack Harry Potter.

### Dungeons

*Main article: Dungeons*

The dungeons of Hogwarts Castle were located under the school, and it was colder there than in the main castle.

#### Dungeon Cupboard

*Main article: Dungeon Cupboard*

This cupboard was a small room off the Dungeon Corridor, just before the Dungeon Hall.

*Main article: Deathday Party Hall*

This was one of the roomier dungeons at Hogwarts Castle. The room was accessible via the Dungeon Staircase. On 31 October, 1992, this dungeon was where Sir Nicholas de Mimsy-Porpington's Nicholas de Mimsy-Porpington's Five-Hundredth Deathday Party was held.

#### Potions Classroom

*Main article: Potions Classroom*

The Potions Classroom was where Potions classes were taught. The classroom used to be square-sized, very large, with large tables and windows. From 1995-1996, the classroom was an oval shape and relatively smaller, with small work tables. In 1996, the classroom was extended, adding space for more work tables.

#### Potions Basement

*Main article: Potions Basement*

There was a storage basement under the Potions classroom at Hogwarts Castle. It was accessible via a trapdoor and it was used to store cauldrons, ingredients and phials.

#### Head of Slytherin's Office

*Main article: Severus Snape's Office*

This office was used by Severus Snape during his long tenure as Potions Master at Hogwarts. It was a gloomy and dimly-lit room found in the school Dungeons. The shadowy walls were lined with shelves of large glass jars filled with slimy, revolting things, such as bits of animals and plants, floating in potions of varying colours.

The office had a fireplace. In a corner, there was a cupboard containing Snape's private stock of potion ingredients. The office was sealed with a spell only wizards could break.

#### Slytherin Common Room

*Main article: Slytherin Dungeon*

The Slytherin Dungeon was located behind a wall in the dungeons of Hogwarts. A password spoken to the wall was required to enter it; whereupon a passage was revealed leading to the Common Room - a low-ceilinged, dungeon-like room with greenish lamps and chairs. The room also contained black leather couches and a fireplace. This dungeon extended partway under the lake, which allowed students to glimpse the inhabitants of the Great Lake.

Off of this room also included the Slytherin Boys' Dormitory.

#### Philosopher's Stone Chambers

*Main article: Philosopher's Stone Chambers*

These chambers were a series of rooms underneath Hogwarts School of Witchcraft and Wizardry that served as the defences surrounding the Philosopher's Stone during the 1991-1992 School Year. There were seven chambers in total that contained an obstacle or task that guarded the stone against being stolen.

1. Fluffy (stationed in the Third-Floor Corridor guarding the trap door entrance to the chambers below)

### Basement

#### Hufflepuff Common Room

*Main article: Hufflepuff Basement*

The Hufflepuff Basement was the Common Room for the Hufflepuff students at Hogwarts. The entrance to the Hufflepuff Basement was hidden behind a stack of barrels. It could be entered by tapping a certain rhythm on the barrels. It was located near the kitchens. The cellar was decorated with yellow hangings and filled with far armchairs. Underground tunnels led off to the students' dormitories and all the doors were perfectly circular, like barrel tops.

This was the only common room Harry Potter did not enter at some point during his years at Hogwarts.

#### Kitchens

*Main article: Hogwarts Kitchen*

The Hogwarts kitchen was located directly under the Great Hall, down the same staircase that led to the Hufflepuff Common Room. It contained tables identical to those in the Great Hall and were directly below them; food had to simply be placed on the tables in the kitchens, and it magically appeared in the Great Hall. The kitchens were staffed by over 100 House-Elves, including Dobby, Winky and Kreacher (after Harry Potter inherited him and ordered him there in 1996).

To gain access to the kitchens, one had to tickle the pear on a fruit portrait, which would then turn into a door knob.

### Boathouse

*Main article: Boathouse*

The Boathouse was an underground harbour at Hogwarts where the boats were stored and docked after bringing the first years to the castle every 1 September. Up until 1995 a portrait of Percival Pratt hung on the walls, concealing a shortcut to the Grand Staircase.

After Pratt's portrait was removed, there were only three entrances to this building: the path outside the Paved Courtyard, the stairs down from the Viaduct Courtyard, and the Great Lake.

### Entrance Hall

*Main article: Entrance Hall*

The Great Hall was a large hall that could easily hold all of the school's students, staff and guests. It had tall walls that reached up to the ceiling, which was enchanted to look like the sky above.

It was the scene of Harry Potter and Lord Voldemort's final showdown, which was the Dark Lord's ultimate defeat. This was because the Elder Wand refused to kill its true master, so Harry was not killed. Since Voldemort was now a mortal man, the curse rebounded on him, killing him once and for all.

### Staffroom

*Main article: Staffroom*

The staffroom was a long, panelled room with mismatched, dark wooden chairs. There was a wardrobe inside it which was once home to a Boggart. The entrance to this room was guarded by two talking stone gargoyles.

### Astronomy Tower

*Main article: Astronomy Tower*

The Astronomy Tower was the tallest tower at Hogwarts, surrounded by a parapet and turret. It is where students studied the stars and planets through their telescopes in Astronomy lessons with Professor Aurora Sinistra. This was usually done at midnight when the stars were best seen. The tower was usually out-of-bounds except for classes. All the way down from the boathouse, one could see the huge window of the Astronomy Tower.

Located within this tower was the Astronomy Corridor, Astronomy Reading Room, Astronomy Classroom, Astronomy Stairwell, Astronomy Department and the Astronomy Room. In 1997, Hogwarts' Headmaster, Albus Dumbledore, was killed here on this tower by his eventual successor, Severus Snape. However, it was planned between Dumbledore and Snape to spare Draco Malfoy being a murderer and spare the headmaster from a slow painful death. This was because Dumbledore's hand was affected by a dangerous curse created by Tom Riddle to protect his Horcrux (Marvolo Gaunt's Ring).

### Bell Towers

*Main article: Bell Towers*

The Bell Towers were two towers that rose over the main entrance to the Herbology Greenhouses. Between the two towers were a set of double wooden doors which led along the Ground Floor Corridor. Inside the left bell tower was Filch's Office.

### Clock Tower

*Main article: Clock Tower*

The Clock Tower did not begin at the Ground Floor level. Because it was placed on top of a hill, the Tower began at the Third Floor level. In the entrance to the Tower, there was a huge space, like an Entrance Hall with flights of wooden stairs at the right and left side. The first landing was at the Fourth Floor level. It was at this landing where the clock's gears and face were.

This same corridor connected the Tower to the remaining castle. Up another flight of wooden stairs was another landing, this time at the Fifth Floor level. It was in this landing that the clock's bells were; some massive gold and copper bells. There was another corridor at this landing; like the other, it linked the Tower to the main castle.

### Dark Tower

*Main article: Dark Tower*

The Dark Tower was a small but high tower near the Transfiguration Courtyard. This tower seemed to be used as a prison. It had several prison cells, with the topmost being at the roof. The cells were not, however, charmed or otherwise protected against breaking-in from the outside. It had seven floors.

### Defence Against the Dark Arts Tower

*Main article: Defence Against the Dark Arts Tower*

Hogwarts Turris Magnus was among the largest towers of the castle. It stood next to the Viaduct Entrance, overlooking the Suspension Bridge and the Training Grounds. It had a semi-circular shape.

The tower was home to Minerva McGonagall's Office on the first floor, the Third Floor Corridor and Serpentine Corridor, Classrooms 3C and 7A, Lost Wands Store and the Ghoul Studies Classroom on the third. A staircase ran through the centre of the tower.

### Grand Staircase Tower

*Main article: Grand Staircase Tower*

The Marble Staircase Tower was one of the many towers of the castle. It was one of the most prominent and recognisable features of the castle, dominating the skyline near the Great Hall and The Quad. The tower was extremely large, spanning all seven floors as well as the basement level and countless attic-level rooms, judging from the many dormer windows in its conical roof. There were three smaller turrets on the roof of the tower.

The Marble Staircase Tower received its name from the Marble Staircase, a large staircase which connected the Entrance Hall to the Grand Staircase. The Grand Staircase itself, consuming most of the space in the tower in a large, rectangular room, spanned at least eight storeys and had large windows that looked out over The Quad.

### Gryffindor Tower

*Main article: Gryffindor Tower*

Gryffindor Tower was located behind the portrait of the Fat Lady on the Seventh Floor. A password was required to enter it, which was spoken to the portrait. A circular hole was behind the painting, leading to the common room, which was a circular room where Gryffindor students could relax after a long day of studying. The common room was full of squashy armchairs, tables, and a bulletin board where school notices, ads, lost posters, etc. could be posted. A window looked out onto the grounds of the school, and a large fireplace dominated one wall.

The Gryffindor dormitories were also located in the Tower, with two doors leading off from the common room that opened to spiral staircases. One of them led to the girls dormitory, the other to the boys. The stairs to the girls dormitories were enchanted to become a slide if any body attempted to climb them, but not vice-versa, since it was deemed that girls were more trustworthy than boys.

### Headmaster's Tower

*Main article: Headmaster's Tower*

The Headmaster's Office was located within this tower. To gain entrance, a password had to be given to a stone gargoyle, which would move aside at the correct password to reveal a spiral staircase with moving steps. The office was a circular room with windows, decorated with portraits of previous Headmasters including Dilys Derwent and Phineas Nigellus Black. Many magical instruments were kept there, such as the Sorting Hat and the Pensieve.

### Hospital Tower

*Main article: Hospital Tower*

The Hospital Tower was one of the many towers of Hogwarts Castle which had a semi-ocular shape. It was located on one side of The Quad and was at the end of the hospital corridor which connected the Clock Tower to the rest of the castle. On the fourth floor of the tower was the Hospital Wing and the school matron's office. There was also a staircase that led to the fourth-floor corridor and, by extension, to the Grand Staircase.

There was also a secret passage behind a bookshelf in the matron's office. The Prefect's Bathroom was located on the fifth floor, just above the hospital wing.

### North Tower

*Main article: North Tower*

The North Tower was the location for Divination classes and the Divination teacher's office. The entrance consisted of a ladder leading through a trap door.

### Ravenclaw Tower

*Main article: Ravenclaw Tower*

Ravenclaw Tower was located on the west side of Hogwarts. The staircase leading up to the common room was presumably located on the fifth floor, and was the location of the Ravenclaw Common Room and dormitories.

The entrance to the room was at the top of a spiral staircase, and was a door without a doorknob or keyhole but a bronze knocker in the shape of an eagle. In order to enter the room, one had to answer a question asked by the eagle knocker; if a student answered wrong, they had to wait for someone who got it right.

### Stone Bridge Tower

*Main article: Stone Bridge Tower*

This was one of the four towers surrounding The Quad. It overlooked the Stone Bridge. The first floor landing of the tower went over here connecting the First Floor Corridor to the Stone Bridge.

### West Tower

*Main article: West Tower*

The Owlery was located on the top of this tower. During the winter months, the tower was very cold, to the point that one had to be careful with ice on the higher landings. A tightly spiralling staircase led from the bottom of the tower on the seventh floor up to a door leading out onto the battlements.

*Main article: Hagrid's Hut*

The gamekeeper's hut was located on the edge of the Forbidden Forest. Rubeus Hagrid, the gamekeeper during Harry Potter's time at Hogwarts, lived here for many years.

### Forbidden Forest

*Main article: Forbidden Forest*

Also known as the Dark Forest or Black Forest, the forest bordered the edges of the Hogwarts grounds. As its name suggests, it was strictly off limits to students - except in the case of detention, or Care of Magical Creatures lessons that occasionally took place there. Of course, with the various dangerous creatures, such as centaurs, Thestrals, Unicorns, Hippogriffs and Acromantulas living in the forest, few students would probably even want to venture into it.

### Greenhouses and Gardens

*Main article: Herbology Greenhouses*

There were at least three greenhouses in which Herbology classes were held, under Professor Sprout's supervision. Greenhouse Three was restricted to students as it housed dangerous plants such as Venomous Tentaculas, Mandrakes, and others.

### Great Lake

*Main article: Great Lake*

The Great Lake was a large body of water located to the south of the castle. It was about half a mile in diameter and the Hogwarts plumbing network drained into it. It was home to a Giant Squid and a colony of Merpeople. The lake was also used as a site of the Second Task of the Triwizard Tournament.

### Quidditch Pitch

*Main article: Hogwarts Quidditch Pitch*

The school had its own Quidditch pitch, where each house's Quidditch teams practiced and played games against each other. Each year would see a total of six inter-house matches, along with numerous training sessions by each house team.

### Quidditch Gate

*Main article: Quidditch Gate*

The Quidditch Gate was the entrance to the Quidditch Pitch. It was flanked by two stone structures which resembled two of the spectacular towers surrounding the pitch. Inside the gate, several trophies and shields were housed. Through the gates led to a steep winding downhill descent from the vicinity of the Wooden Bridge.

### Entrance Gates

*Main article: Entrance Gates*

The Entrance Gates to Hogwarts were located a short distance from Hogsmeade Station. The gates would be opened on the first day of term and carriages pulled by Thestrals would take students up to the castle. The Entrance Gates were made of magnificent wrought iron and were flanked by two columns topped with statues of winged boars. Just a few yards from the gates was a small guardhouse with a tall chimney.

### Clock Tower Courtyard

*Main article: Clock Tower Courtyard*

The Clock Tower Courtyard was a cloister on the base of the Clock Tower at Hogwarts. This cloister seemed to be one of the older parts of the castle, and the ceiling and walls were dilapidated. It also led to the Wooden Bridge.

### Wooden Bridge

*Main article: Wooden Bridge*

The Wooden Bridge was a feature of Hogwarts Castle. The bridge appeared derelict, and was constructed of wood beams which extended to the floor of the ravine it lay across. The roof of the Wooden Bridge was sagging and appeared thatched and tarred. The bridge blended in with the natural environment surrounding it.

The Wooden Bridge began at one end of the Clock Tower Courtyard, at the base of the Clock Tower. At the end of the Wooden Bridge there was a small stone gazebo with benches. Outside of it was the Sundial Garden. Given its unstable look it was possible held up by magic.

### Training Grounds

*Main article: Training Grounds*

This was where Flying classes were taught to first years at Hogwarts by Madam Hooch. The grounds were flat, short-cut grassy areas and were located near the Herbology greenhouses. It was overlooked by the Training Grounds Tower.

### White Tomb

*Main article: White Tomb*

The White Tomb was the only grave at Hogwarts. Located on the shores of the Lake, it was the final resting place of Albus Dumbledore, who willingly gave his life in the service of the Order of the Phoenix fighting Lord Voldemort's Death Eaters in the course of the Second Wizarding War.

## Unknown Locations

### Book of Monster's Repair Workshop

*Main article: Book of Monster's Repair Workshop*

### Cauldron Cupboard

*Main article: Cauldron Cupboard*

The Cauldron Cupboard was one of the rooms seen on the Marauder's Map. It was possibly a store room where cauldrons were kept. It is possible that the cupboard was close to the Potions Classroom or Snape's provisions cupboard.

### Stink Bomb Store

*Main article: Stink Bomb Store*

The Stink Bomb Store was one of the rooms seen on the Marauder's Map. It was possibly an illegal store, because when a Hogwarts Professor burst in, the students inside it ran out of the room. It was (possibly) the place where Stink Bombs and Dungbombs were sold.

### Serpentine Corridor

*Main article: Serpentine Corridor*

This was a wide, curved corridor in the Hogwarts Turris Magnus at Hogwarts Castle. One could access the Defence Against the Dark Arts, Ghoul Studies and Arithmancy classrooms through this corridor, as well as Lost Wands.
