This British city is situated on the north bank of the Thames, next to a sea port and a fortress. Initially built to house railway and port workers, Tilbury became a major point of defense for England, along with neighboring town Gravesend, due to the narrowness of the Thames at this point. The forts constructed in Tilbury and Gravesend under Henry VII, due to this narrowness in the river, were of major importance as defenses during several wars, including during the Armada campaigns of 1588.

Leixões is Portugal's largest artificially constructed harbor and is situated near the city of Porto. Porto is known for its famous port wine. The port city is characterized by its picturesque quaintness. Closely packed houses, steep cliffs and numerous terraces contribute to this cosy atmosphere.
