A beach is usually a place where there is sand and a water source. Many people build sand structures at the beach using the sand and water from ocean or lake and make sand castles.
A long structure built out from the beach that you can walk along is called a pier. Piers are typically made of wood or concrete and extend over the water, providing a space for recreational activities, fishing, or enjoying scenic views. They often feature amenities like benches, shops, or restaurants, enhancing the beach experience for visitors.

A groyne is a structure which is built at least partially underwater to inhibit water flow and control the movement of sediment. The purpose of a groin at the beach is either to create more beach or to prevent the erosion of an existing beach.
It was built in 1873 and finished in 1875

A wall-like structure that extends into the ocean and traps sand and small rocks on a beach is called a groin. Groins are typically built perpendicular to the shoreline to reduce erosion and encourage sediment deposition on the beach side. They help maintain beach width and protect coastal areas from wave action. However, they can also lead to increased erosion downshore.
The structure is how it's built and what it's built of. The function is what it does and how it does it.
Whaleback is an anagram for 'beach walk'.
