Ravenclaw Tower Located at the very top of the West Tower, Ravenclaw's Common Room is accessible through a hidden spiral stairwell between two gargoyle statues. Once the password is given, the stairwell lowers itself from the ceiling, allowing entry to the Common Room<br/><br/>The start well leads up into a large central room with sturdy oak tables with raven engraved legs and the crest enchanted into the center to show without disrupting the writing surfaces.  The  walls of the hall are covered in the tapestries donated by the alumni who had achieved great advancements in the worlds understanding of magic, a great honor to be recognized for all time within Ravenclaw.  Where there are not tapestries, there are book shelves, filled with the books donated again by the alumni, often even including books not included within the school library, though not as extensive.  They also include the first copies of any book ever published by a Ravenclaw.<br/><br/>There are two staircases opening off the common room into the Tower itself: the boys' staircase, on which the seven boys' dormitories are located (one for each year) and the girls' staircase, on which the seven girls' dormitories are located (one for each year). The girls' staircase is under a spell so that if a boy sets foot on it and persists for a few steps, a wailing klaxon goes off and the staircase temporarily Transfigures itself into a stone slide, sending him and anyone else on the stairs sailing to the bottom. According to Hogwarts, A History, the founders believed that girls were more trustworthy than boys, so that while the girls' staircase is enchanted to prevent boys from getting in, the boys' staircase does not carry a reciprocal enchantment. Each dormitory is a round room with windows looking out onto the grounds, and containing four-poster beds.
