While both are marine structures extending into bodies of water, they serve distinct primary functions. A pier is a raised walkway supported by pillars or pilings built out over the water, designed primarily for people to stroll, fish, or allow boats to dock alongside passengers. In contrast, a jetty is typically a solid, massive barrier constructed of rock, earth, or concrete extending from the shore to protect a harbor entrance or navigation channel from waves and erosion.
