It was back in 1500 when ships of many nations were stopping off in what is now South Africa to take-on water and whatever food they could barter, that a Portuguese bloke came up with the idea of putting mail for delivery back home, or from whence they'd recently come, in an old seaman's boot under a tree in what is now Mossel Bay; ships heading in the opposite direction would clear the boot and deliver its contents to the countries to which it was addressed
The first letter left this way by Pedro de Aitade, a naval commander, was addressed to the King of Portugal. It was found a year later in the boot by the Third East India Fleet, and doing the right thing, they had it delivered to Portugal and the King.
Today a large stone replica of the original boot stands on de Aitade's original boot site – 509 years after he left the first letter there in 1500 – and mail posted in this boot-shaped Post Box is franked "Post Office Tree Mossel Bay."
