A harbor or harbour (see spelling differences), or haven, is a place where ships, boats, and barges can seek shelter through stormy weather, or else are stored for future use. Harbors can be natural or artificial. An artificial harbor has deliberately-constructed breakwaters, sea walls, or jettys, or otherwise, they could have been constructed by dredging, and these require maintenance by further periodic dredging. An example of the former kind is at Long Beach Harbor, California, and an example of the latter kind is San Diego Harbor, California, which was, under natural conditions, too shallow for modern merchant ships and warships.
Harbors and ports are often confused with each other. A port is a facility for loading and unloading vessels; ports are usually located in harbors.
Artificial harbors are frequently built for use as ports. The largest artificially created harbor is Jebel Ali in Dubai. Other large and busy artificial harbors are located at: Rotterdam, The Netherlands; Port of Houston, Texas; Port of Long Beach, California; and Port of Los Angeles in San Pedro, California.

Buildings come in a wide amount of shapes and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, to land prices, ground conditions, specific uses and aesthetic reasons.
Buildings serve several needs of society – primarily as shelter from weather and as general living space, to provide privacy, to store belongings and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the outside (a place that at times may be harsh and harmful).
Ever since the first cave paintings, buildings have also become objects or canvasess of artistic expression. In recent years, interest in sustainable planning and building practices has also become part of the design process of many new buildings.
