Students travel to and from Hogwarts through a steam powered train, known as ''Hogwarts Express''.<ref>{{cite web |last1=Rowling |first1=J.

Rowling has described Hogwarts as a "huge, rambling, quite scary-looking castle, with a jumble of towers and battlements". She said the castle is supported by magic.<ref name="scholastic-chat-1">{{cite news |last=Rowling |first=J. K. |date=3 February 2000 |title=Transcript of J. K.

A subterranean area of the castle known as the Chamber of Secrets is introduced in the second novel, ''[[Harry Potter and the Chamber of Secrets]]'' (1998). In the novel, the young student [[Ginny Weasley]] is forced to open the Chamber by the [[Dark arts (Harry Potter)|Dark]] wizard [[Voldemort]]. From the Chamber emerges a deadly [[Magical creatures (Harry Potter)#Basilisk|Basilisk]], which attacks students until Harry kills it. A magical room called the {{Visible anchor|Room of Requirement|text=Room of Requirement}} is also located in Hogwarts. It only appears when someone needs it, and contains whatever the person requires. In ''[[Harry Potter and the Order of the Phoenix|Order of the Phoenix]]'' (2003), Harry holds meetings of his student group Dumbledore's Army in the Room of Requirement. In ''[[Harry Potter and the Half-Blood Prince|Half-Blood Prince]]'' (2005), [[Draco Malfoy]] uses the room to hide and repair a [[Vanishing Cabinet]], which allows him to smuggle Voldemort's [[Death Eaters]] into Hogwarts.
