The House Cup is an annual award presented at the end of the school year to the Hogwarts House that has accumulated the highest number of House Points. The competition fosters a sense of community and rivalry among the four houses: Gryffindor, Hufflepuff, Ravenclaw, and Slytherin. The official score is tracked publicly in the Entrance Hall by four giant, enchanted hourglasses, one for each House. Instead of sand, these hourglasses are filled with precious gems corresponding to each house's colours:
Whenever a student earns or loses points, the jewels in their respective hourglass magically fall to the bottom bulb or rise to the top bulb, providing a constant visual representation of the standings. The prize for winning the House Cup is primarily one of honour. During the End-of-Term Feast, the Great Hall is decorated with the colours and emblems of the winning House. While a physical trophy is implied by the name, its specific appearance is not described in the novels.
The competition is based on a system of House Points, which are awarded or deducted based on students' actions throughout the school year.
Points can be awarded or taken away by members of the Hogwarts Staff, the Headmaster, the Head Boy, the Head Girl, and Prefects. The final point totals are announced by the Headmaster during the End-of-Term Feast, where the winner is declared.
Before Harry Potter's first year, Slytherin had won the House Cup for seven consecutive years. The competition results during Harry's time at Hogwarts were as follows:
The House Cup is a fundamental part of the Hogwarts experience and serves several key narrative functions in the series.
