parapet
Rooftop protective wall
A parapet is a low protective wall along the edge of a roof, bridge, balcony, or fortification.
In military architecture, parapets shielded soldiers while allowing them to fire over the top: The defenders crouched behind the parapet.
The word extends to any similar barrier at a dangerous edge: She leaned over the parapet to watch the river below.
