abri
Excavated protective cavity
An abri is a shelter, particularly a military dugout or bunker providing protection from enemy fire.
The word comes directly from French and appears mainly in military contexts or historical accounts of warfare: The soldiers took cover in a hastily constructed abri.
In archaeology, abri sometimes refers to a rock shelter or overhang used as a dwelling site.
