The Gryffindor Common Room is “cosy, round room” (PS7). It contains a lot of squashy armchairs, a fireplace, and tables. The fireplace is connected to the Floo Network, but as it is extremely public except in the dead of night. There’s also a notice board, for public announcements such as the date of the next Hogsmeade weekend, but also for notices from individual students seeking to buy or sell secondhand books, or trade Chocolate Frog cards, or similar. The Common Room is where Gryffindors spend their free time and where they work on their homework.
