Corridors

A moving tapestry of Barnabas the Barmy, depicting his foolish attempt to train trolls for the ballet, hangs on the 7th floor of Hogwarts Castle, opposite the entrance to the Room of Requirement. That stretch of corridor has a window on one end and a man-sized vase at the other. here's a statue of Lachlan the Lanky on the seventh floor to the right of the top of the stairs, between the stairs and the Fat Lady's portrait. another corridor on the seventh floor is the location of the gargoyle which guards the entrance to the Headmaster's office.
