The Clock Tower was one of the older features of Hogwarts Castle. Within the tower lay the mechanism that ran the antique clock. There was an old courtyard at its base, and at the top was the clear glass dial of the clock. There was space between the clock's movement and the dial for a person to either repair the clock or to stand and look out over the courtyard. There were five bells in the clock tower of various sizes; these bells appeared to have been made of copper, as the bells were rather oxidised. The Clock Tower chimed every half hour and struck a small bell at the beginning and conclusion of class sessions. What powered the clock's mechanism is currently unknown, but it is presumed to be weight-driven.[1]


The tower did not begin from the ground floor level. Because it was placed on top of a hill, the tower began on the third floor level. If one entered the tower, there was a large hall with flights of wooden stairs at the right and left side, and the pendulum of the Clock Tower could be seen slowly swinging as well. The first landing was on the fourth floor level. It was at this landing that were the clock's movement and transparent dial. A long corridor with the entrance to the Hospital Wing was at this landing. This same corridor connected the tower to the rest of the castle.[2][3]

If one went up another flight of wooden stairs, one would get to another landing, this time on the fifth floor. It was in this landing that were the clock's bells; four massive gold and copper bells for chiming and striking the hours and the suspension spring of the pendulum. There was another corridor at this landing; like the other, it linked the tower to the main castle.[2]

Timekeeping wise, the clock had a visible pendulum swing of 46 beats per minute, due to the length of the pendulum.[1]

During the 1993–1994 school year, the Clock Tower Courtyard was where students waiting to visit the village of Hogsmeade would gather.[1]

Battle of Hogwarts

The Clock Tower's destruction during the Battle of Hogwarts

During the Battle of Hogwarts on 2 May 1998, the Clock Tower was heavily damaged, especially on the front side, by Death Eaters: much of the clock face was obliterated, the clock mechanism was badly damaged and one of its bells somehow ended up at the Entrance Courtyard. However, the bell could have also come from the Bell towers. It is presumed that the tower was reconstructed and the clock mechanism fully restored to working order sometime after the battle concluded.[4]
