In the 1931 film, where is the monster finally destroyed?

In the 1931 film Frankenstein, the monster is finally destroyed—or apparently destroyed—inside a windmill set ablaze by the villagers. After the Monster attacks Henry Frankenstein and carries him to the windmill, Henry is thrown from the tower. The wooden blades break his fall, leaving him alive but injured.

The pursuing mob then traps the Monster at the top of the windmill and sets the structure on fire. The final image strongly suggests that the Monster has died in the flames, although later Universal sequels reveal that he survived. Thus, “a windmill” is the canonical answer for the film's climactic destruction scene.

The sequence follows the accidental drowning of Maria, a child who had innocently played with the Monster. Her father raises the alarm, and the villagers form a lynch mob. The castle, cave, and church are not the location of this final confrontation. The memorable burning windmill became one of the defining images of the Universal Frankenstein cycle.
