La Coruña port existed in roman times. The Hercules Tower, a roman lighthouse which is thought to have been built during the first century AC, shows the relevance of the area during that time. The relevant port of the region was present Betanzos (Brigantium), as its ria was less silted and ships were smaller. During the Middle Ages the city becomes more relevant, and the opening of the American trade after the end of the monopoly of Seville and Cadix helps. Around the mid XXth century the port occupies most of the southern bay, protected by the peninsula; this is the last vision of Spain for thousands of Galicians migrating to America. During the 1960’s a large jetty is built to enlarge he port, and a new oil refining plant gives relevance to liquid bulks. This also leads to several tanker accidents that pollute the air and the ocean. The transition to democracy with the death of Franco brings regional devolution and the loss of the regional capital to Santiago, with the transfer of many public jobs. During the last decade a new port has been built, west of the historic bay, in part to reduce risks (oil wharfs are linked to the refining plant by a pipeline near homes), but the location is clearly into the metro area. The presence in that metro area of the headquarters of Inditex, the textile group owning Zara, helps to a certain degree to weather the current economic crisis.
Brest is first mentioned in history as a roman encampment at the end of the IIIrd century AC. The estuary of the river Penfeld made for a good natural harbour for the ships of the age. In 1593 Henri IV incorporates Brest as city, and in 1631 Richelieu establishes an arsenal on the Penfeld’s banks. The city plays a relevant role for the fleets helping the United States in their Independence War. The XIXth century starts under the British naval blockade, hurting the port; this changes under the second empire, with a wider sea trade, new rail lines and bridges over the Penfeld. Urban growth goes crosses the historic walls. Bigger ships make the need for a larger port, out of the Penfeld estuary, and new warfes are open on the large bay. During WW2 the port becomes a German Naval base and is bombed by the allies, which destroy a large portion of the city, later rebuilt. The creation of the Oceanic Strategic Force in 1972 leads to the creation of the new nuclear submarines base on Ile Longue, south of the bay. The reduction in military budgets hurts the city.
Duluth receives its name from the first European explorer of the area, a XVIIth century French soldier which was called “Sieur du Luth”. The first known residents were the Anishinaabe tribe, which played a mediating role between the French and other Indian nations. Fur trade (especially beaver) was a relevant part of that early trade. In the mid XIXth century cooper mines, new locks allowing the arrival of large ships to lake Superior and plans for new rail linking the city to the Pacific (creating so a inter-ocean port) helped fuel the inception of the city. The port and the city grew exporting ore (mainly iron) and cereals. The crisis of the traditional heavy industry at the end of the XXth century has touched the city, but it is to a certain degree compensated by tourism and services to the metro area.
Puerto Montt had some population prior to the arrival of the Spanish (southern Chile was never really incorporated to the Empire). Around the mid XIXth century German colonists started arriving to the area, and the city is incorporated in 1853. The rail line to Osorno starts operation in 1912. During the 1930 there is a substantial transformation of the waterfront, with new embankments, rail lines, a wharf and the dredging of the Tenglo channel. The city becomes in 1974 the capital of the Xth region (Los Lagos). Since 1985 the salmon production becomes important (and the plague problems for the species test the local economy), with other more traditional activities as agriculture, cattle or wood being also relevant. Tourism has become a relevant asset too.
