Bell towers

The Bell Towers are two square towers which rise over the Greenhouses of Hogwarts Castle.

In the first two films, the towers were quite short and had small "balcony-like areas" below the turrets at the top.

From the Prisoner of Azkaban film onwards, they changed to being taller, thinner, having taller spires and no "balcony-like area".

Behind the Scenes
In the Half-Blood Prince film, the Charms tower changed into another Bell Tower, but this one was slightly shorter.
