Most piers jut out from the shore to provide access to offshore areas. They are typically supported by pillars or piles. These structures serve many vital roles in human society. They are used for fishing, docking boats, and moving passengers or cargo. They also provide space for oceanside recreation. Because they serve different needs, the meaning of the word "pier" can change depending on where you are in the world.

The physical design of a pier is very important for its function. Unlike a solid quay or a wharf, a pier has an open structure. This design allows tides and currents to flow through the piles relatively unhindered. Solid foundations can act as a breakwater, which might cause silting. Silting is when sand or mud builds up in the water. Some piers are even built as floating piers. These structures rise and lower along with the tide. This movement ensures that boat lines do not become too tight or too loose. If a line is too tight, it could pull a boat out of the water. If it is too loose, the boat might bang against the pier.

Piers can be categorized into different groups based on their main purpose. Working piers are built to handle passengers and cargo. These can be large individual piers or smaller finger piers. Long piers are often found in ports with large tidal ranges. They stretch far offshore to reach deep water during low tide. Finger piers are usually shorter and are used in ports with smaller tidal ranges. These provide more space for ships to berth along the shore. Many working piers were once used for general cargo. However, the rise of container shipping has made many of them obsolete. Some have been converted into pleasure piers for tourists.

Pleasure piers are designed specifically for fun and relaxation. These became very popular in Great Britain during the early 19th century. This popularity grew because of the introduction of steamships and railways. These new technologies allowed many people to visit seaside resorts. Early pleasure piers were often made entirely of timber. Some later used a mix of iron and timber. Today, many pleasure piers include amusements, theaters, and even roller coasters.

For example, the Galveston Island Historic Pleasure Pier in Texas has 15 rides and carnival games.

The history of piers includes many significant early structures. Ryde Pier on the Isle of Wight opened around 1814. It was built as a landing stage for ferries and is still used today. The Trinity Chain Pier was built in 1821 near Leith. The Brighton Chain Pier was completed in 1823. The Margate Jetty, which opened in the 1820s, was originally made of timber. It later became an iron and timber structure in 1855. While many historic piers have been lost to storms or time, some remain iconic. The Southend-on-Sea pier in England is the longest iron pleasure pier still remaining. It was first opened as a wooden pier in 1829.

There are many impressive records regarding the size and scale of piers. The Progreso Pier in Yucatán, Mexico, is the longest pier in the world. It extends more than 4 miles into the Gulf of Mexico. This pier is essential for the fishing and cargo industries in the area. In England, the Southend-on-Sea pier reaches 1.3 miles into the Thames Estuary. On the West Coast of the United States, the Santa Cruz Wharf is the longest. Some piers are also massive centers for tourism. In 2017, the Brighton Palace Pier was a major attraction. It had over 4.5 million visitors in the previous year.

Piers also connect to other important scientific and environmental systems. In Australia, piers at Southport and the Tweed River serve a special purpose. They support equipment for a sand bypassing system. This system helps maintain the health of sandy beaches and navigation channels. This shows how man-made structures can interact with natural coastal processes. Whether they are used for heavy industry or for a simple day of fishing, piers remain a vital part of our relationship with the sea.
