Anotations

Scope note:

Substantial, man-made banks or landing stages, typically built of stone, lying alongside or projecting into water for loading and unloading ships. For structures that are not man-made banks, but built in similar locations and for similar purposes, use "wharves"; use "piers (marine landings)" for lighter structures that extend out over the water.
