The prefects bathroom is only for prefects but sometimes regulare students will sneak into here and pull pranks on the prefects they don't like.

The Clock Tower Courtyard is a cloister on the base of the Clock Tower at Hogwarts School of Witchcraft and Wizardry. This cloister seems to be one of the older parts of the castle and the ceiling and walls are delapidaded. It also leads to the Covered Bridge.

The Covered Bridge is a feature of Hogwarts Castle. The bridge appears derelict, and is constructed of wood beams which extend to the floor of the ravine it lays across. The roof of the Covered Bridge is sagging and appears thatched and tarred. The bridge blends in with the natural environment surrounding it.

The Covered Bridge begins at one end of the Clock Tower Courtyard, at the base of the Clock Tower. At the end of the covered bridge there is a small stone gazebo with benches. Outside of it is the Stone Circle.

The Stone Circle is, as its name suggests, a circle of giant stones that is in the grounds of Hogwarts Castle, just outside of the Covered Bridge. It seems as though the circle may be a sun dial. This cromlech stands on top of a hill that allowed a person to see Hagrid's hut on a higher place
