Before commercial air travel (literally) took off in the 1950s, travellers would take leave of their loved ones with a “Bon voyage!” and board a ship.
One of the great shipping lines to link Africa and Europe in the 20th century was the Union-Castle Line. It ferried passengers, mail and cargo between Cape Town and Southampton in England, stopping at various East African ports on the way.
Although the name “Union-Castle” became synonymous with seafaring holidays and African safaris, its inception is linked to mail delivery.
