Piers are structures built over water, typically extending from the shore into a lake, river, or ocean. They are often made of wood or concrete and serve various purposes, such as providing a place for boats to dock, allowing people to fish, or offering a scenic spot for walking and enjoying the view. Piers can be found in many coastal towns and are popular destinations for tourists and locals alike. Many piers also feature amenities like restaurants, shops, and amusement parks, making them lively hubs of activity. Some famous piers, like the Santa Monica Pier in California, are known for their iconic attractions and vibrant atmosphere, drawing visitors from all over.
