The first extension of the Port after the First World War.

The First World War (1914-1918) caused a serious crisis in maritime traffic on a global scale. There was less merchandise and too few ships, which had a negative effect on the orange trade since it became extremely difficult to get the product to its principal markets. After the armistice, however, the port, little by little, not only recovered its former level of activity but this increased to the point where, in 1923, two shipping lines were making regular bi-weekly stops in Castellón. As a result of this increase, it was decided to draw up a plan to expand the port by lengthening the Levante breakwater in order to make possible the use of the exterior basin once a transverse harbour wall had been constructed. It was necessary, however, to overcome the disastrous effects of the civil war before any further development was possible.

In the 1950s the engineer Modesto Vigueras drew up another project based around the prolongation of the exterior breakwater. In the 1970s the new fishing harbour was established, once the new ‘Muelle de Costa’ (Coast Quay) had been completed and the fish quay was established there, where it remains today.
