Fog signal station

A fog signal station is a facility located near navigational waterways, such as harbors or coastal areas, that provides auditory signals to assist vessels in navigation during conditions of low visibility, such as fog or heavy rain. These signals are crucial for preventing collisions and helping mariners determine their position. Fog signals typically consist of sound-producing devices, which can include horns, bells, or whistles that emit recognizable patterns or sounds at regular intervals.
