Those that have never lived in a port city often have no idea on how variable their landscape is. A ship of a certain size can be longer and higher than many buildings, and its skyline can change with the arrival of sizeable volumes of colours that can be quite different from those of the buildings. However, this game is far from being reserved to ships.
Ports are, as cemeteries, areas in which architecture develops along particular lines. On the former, aesthetic rules can be taken far from what is allowed in the city of the living; in ports, what is utilitarian clearly takes control, as well for buildings as for any foreseeable contraption. There are outstanding port buildings, which have outstanding architectures, but most are rather limited in that sense, with multiple additions and improvements that are often without much architectural interest. When you focus on mobile contraptions, especially on freight ports, a world of vehicles, cranes and bridges opens and can easily become surprising.
Some days ago, walking by the port of La Coruña, I saw one of the new cranes in motion. Just a few decades ago the former, wood-cabin cranes were substituted by new, higher, steel ones, that as the former moved along railroad tracks. About a decade ago new cranes, a bit higher, moving on tires, were introduced. Seeing one such machine when they go from one wharf to another, moving very slow, is not without reminding the motion picture “Despicable me” and Gru’s car: high, with a permanent air of instability, and in fact seeming a toy… but for its overwhelming weight.
On the other side, the machinery for solid bulk, which sometimes can create allergic outbreaks if dispersed through the air, has a clear urban presence.
When ports are on busy circulation corridors, the need for bridges appears, and so that for complex solutions. In Duluth the Aerial Lift Bridge is one of the city icons. It was built to grant access to the Minnesota Point peninsula after the opening of a navigation channel through its base. The first years it was a transporter bridge, to be later transformed in the current car bridge with a vertical motion platform that adapts to the air draft of passing ships. Besides, as in many ports in this area of the great lakes, where iron ore is one of the most common bulk freights, the contraptions that allow the transfer of the load from trains to ships are simply impressive (something that can be well perceived on this video about a different port in Michigan http://www.youtube.com/watch?v=rzWwTOt39Es&list=PL7eOOJxsVrlgY0de0Osk7DTF8l2r9ksOb&feature=share&index=3). Such wharfs can only be seen (but not in active) in zones of Spain like Huelva or Almería.
Brest also has a moving bridge at Recouvrance, with a more contemporary structure. It is the main French port for naval repair, so it is common to see many large ships; as a relevant naval station, there are also many other “toys”, but not always visible.
In Puerto Montt the port has less such contraptions; but you can see the Andean volcanoes on the background (something the other three ports can hardly compete with…)
