Various types of artwork are displayed in the halls of Hogwarts, including paintings and sculptures. Many if not all of these are magical and are animated in some way. Apparently there are no art classes at Hogwarts, although Dean Thomas is known for being a good artist.
paintings & other artwork
- bowl of fruit, painting of
One of a series of cheerful paintings (mainly still lifes featuring food, although "still life" is a rather relative term to use in the wizarding world) that hang in a broad stone corridor to the left of the staircase leading one flight down from the Entrance Hall. The painting of the bowl of fruit will open to reveal the entrance to the Hogwarts kitchens if the pear is tickled (GF21)
- landscape with trees
On the fourth floor. Peeves saw the Fat Lady running through this painting after she fled from Sirius' attack (PA9)
- Entrance to the Hufflepuff common room
Like the Gryffindor common room, the entrance to the Hufflepuff common room is hidden behind a painting. In the case of Hufflepuff, the painting is a still life and it's located in a corridor somewhat below the level of the Entrance Hall, near the kitchens (BLC).
- Argyllshire, map of
On second floor, Fat Lady hid here after being attacked by Sirius (PA9)

a lost-looking wizard with his gloves on the wrong hands near the prefects' bathroom on the fifth floor
- Rowena Ravenclaw wearing her diadem
Life-size white marble statue in Ravenclaw Tower (DH29)
- Gregory the Smarmy, statue of
Stands in front of the entrance to a secret passage that the twins say they found during their first week at Hogwarts (PS9)
- griffin, large stone statue of (PS10)
- humpbacked witch (probably Gunhilda of Gorsemoor), statue of
Halfway along a third-floor corridor between the staircase leading from the Entrance Hall and the way to Gryffindor Tower, this statue conceals the entrance to a secret passage leading to Honeydukes' cellar (PA10)
- Lachlan the Lanky
Located on the seventh floor very close to the head of the stairs leading down to the sixth floor. Ron hid from the twins behind it to avoid being teased about wanting to try out for Keeper (OP13)
- Paracelsus, bust of
Located halfway down the corridor leading from the Gryffindor common room to the shortest route to the Owlery; requires a right turn from the common room (OP14)
- Wilfrid the Wistful
Located between Gryffindor Tower and the Owlery, requires a left turn from the common room. Mrs. Norris disappeared behind this statue while setting out to report to Filch after encountering Harry on his way to the Owlery, so a secret passage or short cut may be in its vicinity (OP14)
- A stone gargoyle protects the entrance to the Headmaster's office, and will leap aside only if given the proper password; this statue has not spoken to Harry when spoken to or even when kicked (CS11)
- two stone gargoyles stand on either side of the door of the staffroom; they challenge any student who tries to knock on the door (OP17, DH31)
- winged boars flanking the entrance gates (PA5)
- McGonagall animated the statues and armour to fight in the Battle of Hogwarts (DH30) using a Piertotum Locomotor spell.
Tapestries on the walls of the corridors sometimes hide secret passages (PS9, CS8, OP28, HBP14), including the entrance to the staircase with the trick step (GF12, 25). There are tapestries in the Gryffindor common room (HBP9).
Barnabas the Barmy, moving tapestry of
depicting his foolish attempt to train trolls for the ballet, hangs on the seventh floor of Hogwarts Castle, opposite the entrance to the Room of Requirement (OP18, 26, HBP20).
