Within the Hogwarts School of Witchcraft and Wizardry, there exist four houses, each having been founded by one of four of the greatest witches and wizards of the age.  These witches and wizards wished to bring together students of magical talent to be instructed in the various fields of magic, and therefore created these houses for students possessing personal traits similar to that of their respective founders.  One of these houses is the noble House of Godric Gryffindor.  To belong to the House of Gryffindor, a witch or wizard must possess the traits described in the lyrics of the following song sung by the sorting during the Sorting Ceremony held for the first years at Hogwarts:

You might belong in Gryffindor,
Where dwell the brave at heart,
Their daring, nerve and chivalry
Set Gryffindors apart

–The Sorting Hat

According to this song, those students whom are sorted into the Gryffindor House possess courage, bravery, and chivalry as their dominant traits, though sometimes, as demonstrated by the actions of Gryffindor members Fred, George, and Ron Weasley and Harry Potter, they take their actions to the point of recklessness.  The house coat of arms has a red and gold background, said to represent fire, with the picture of a lion, the symbol of courage, on the front.

Each house has a large dormitory with a concealed entrance somewhere within the castle.  The Gryffindor Dormitory and Common Room is located on the seventh floor of the castle, in Gryffindor Tower, where its entrance is hidden and password protected behind a swinging portrait of a Fat Lady in a pink dress.  The Commom Room is the main meeting place for the students of Gryffindor and is decorated with fluffy arm chairs, tables and desks, and a large fireplace.  On either side of the Common Room a set of stairs leads up to the boys and girls dormitories.
