Location from harry-potter-chamber-of-secrets by
The main dining and assembly hall of Hogwarts, where the enchanted ceiling mirrors the sky, the Sorting Ceremony takes place, and Molly Weasley's Howler echoes off every stone surface.
The Great Hall is where Hogwarts happens -- feasts, Sorting, Dumbledore's speeches, the arrival of morning post by owl. This year it is also where Ron receives a Howler from his mother that makes the entire school go silent, where Lockhart's Valentine's dwarves ambush students between courses, and where the tension of the petrification crisis hangs over every meal. Students watch each other nervously. The Slytherin table is louder than usual. The Muggle-borns sit closer together.
A cavernous stone hall lit by thousands of candles hovering in midair. Four long wooden tables run the length of the room, one for each house, with a raised staff table at the far end. The ceiling is bewitched to reflect the sky outside. Golden plates and goblets appear at mealtimes. Banners in house colors hang from the walls.
