Covered way

Extracted from the Wikipedia article Covertway.
In military architecture, a covertway or covered way (French: chemin couvert, Italian: strada coperta) is a path on top of the counterscarp of a fortification. It is protected by an embankment which is made up by the crest of the glacis. It is able to give the fort's garrison a position beyond the ditch, as well as a continuous line of communication around the outworks.
