Banquette

In fortification, a banquette is a little foot path or elevated step along the inside of a rampart or parapet, by which the musketeers get up to view the counterscarp, or to fire on the enemies in the moat. These are generally a foot and a half high, and almost three feet wide.

A banquette may also be an upholstered bench or a footbridge.
