Lorient, a city of concrete

The birth and destruction of a city.
Lorient was created in 1666 and destroyed in 1943. Its creation stemmed from the purchase of land by the Compagnie des Indes in order to build a port for trade with the east (l'orient').
In 1943 Lorient was bombed by British allies to destroy the German submarine bases. Five weeks of bombing required twenty-five years of re-building.
And to achieve this as quickly as possible, the buildings are mainly constructed using concrete.
