The Great Hall is a large hall with four long tables where students of each House sit during the day and at mealtimes. The staff table is at the front, where the entire Hogwarts staff sits. There is a throne-like chair in the centre of the table where the current Headmaster or Headmistress sits. The ceiling of the Great Hall is covered with candles and it is enchanted to look like the sky above. To the left of the table is a door which leads to a chamber with portraits. From the staff table, the House tables are as follows (from left to right): Gryffindor, Ravenclaw, Slytherin, Hufflepuff. There are small windows around the side of the hall, and a large window behind the staff table where the light shines through, and a podium carved with an owl is put right in front of the Headteacher's chair, where they make their announcements. During the Hallowe'en feast, the hall is festooned with sweets-filled pumpkins, bats, orange streamers, water snakes and many other Hallowe'en-related decorations. At Christmas, before and during the holidays, twelve large Christmas trees are placed around the room.
