Maritime spaces are socially constructed by humans and refer to seas and islands, coasts, port cities and villages, as well as ships and other human-made marine structures. Social interaction with marine environments and living beings, e.g. in a symbolic, cultural or economic manner, has led to the emergence of spatial structures which affect the knowledge, beliefs, meanings and obstinately patterns. Those structures shape mutual expectations of human beings and form the perception, imagination, or memory of inhabitants of maritime spaces. They enable or restrict human action, construct people’s everyday life, their norms and values, and are changeable.
