"You might belong in Gryffindor, Where dwell the brave at heart, Their daring, nerve, and chivalry Set Gryffindors apart"
So said the Sorting Hat. Gryffindor, one of the Hogwarts School houses, was founded by Godric Gryffindor. The emblematic animal is a lion, its house colours are scarlet and gold. And Sir Nicholas de Mimsy-Porpington, also known as "Nearly Headless Nick" is the House ghost.
And of course, Gryffindor is well-known as the house that Harry Potter, Hermione Granger and Ron Weasley were sent to by the Sorting Hat!!
