Other forms: parapets
A parapet is a low wall along the edge of a roof or bridge. Lean on the parapet, over the parapet, a stone parapet.
Its job is to stop people and things falling, and building rules set its height. In fortification it was the wall soldiers fired over, which is where put your head above the parapet comes from — meaning to risk exposure by speaking out. Note that the Italian means to guard the breast.
