The pier is an iron timber structure raised above water level supporting a deck, it is connected to the land and acts as an access to docking boats. In England between 1850-1900 more than 100 pleasure piers used as seaside resorts were built. Even though their primary function was for promenading and escaping the toxic fumes of the industrialized city, they quickly became much bigger structures where more activities could take place. The large platforms where and are still today used as amusement parks, casinos etc…Extending to the sea and enabling life in an otherwise hostile environment was also a way of demonstrating the extent of what the new technology of cast Iron could achieve.
The roughness of the environment through time also means that the degradation of the object is unavoidable. The resilience of the main structure is therefore primordial even if the secondary structure can degrade itself and be replaced if need be.
These structures have an ability to adapt their shape or program depending on the situation for instance the decking of some piers were removed during world war II to prevent any enemy landing on them.
