A vast hallway that winds through the ground floor. Ends in a staircase leading to the basement and dungeons.

Located off the Entrance Hall, opposite the Great Hall. Where first years wait to be sorted by the hat.

Vast chamber with an enchanted ceiling that mirrors the sky outside. Four long tables for the four houses. Closest to the doors from the Entrance Hall is Slytherin, then Ravenclaw, Hufflepuff, and next to the far wall, Gryffindor. The teachers sit at the High Table, a table on a raised platform at the front of the room. There are windows into this room from the lawn outside.

An enclosed area set in front of the main doors. from here students can take a covered bridge out into the grounds, or just stay and mingle. There is a fountain and many places to sit.

Four giant hourglasses - one for each House - stand in niches in a corner opposite the main doors. Each hourglass is filled with gemstones rather than sand, one gemstone in the lower bulb for each House Point currently held by that House. Gryffindor's contains rubies, Ravenclaw's sapphires, and Slytherin's emeralds. Presumably Hufflepuff's hourglass contains some sort of yellow gemstone.

long panelled room with mismatched, dark wooden chairs. there is a large wardrobe, sometimes inhabited by a boggart. This where where teachers and the like come to discuss things.
