In 1899, architect FW Ortloff's sea wall - better known as the Mole - was intended to enhance Swakopmund's poor harbour and create a mooring place for large cargo vessels. Unfortunately, Mr Ortloff was unfamiliar with the Benguela Current, which sweeps northwards along the coast, carrying with it a load of sand from the southern deserts.
Within less than five years, the harbour entrance was choked off by a sand bank and two years later, the harbour itself had been invaded by sand to create what is now called Palm Beach. The Mole is currently used as a mooring for pleasure boats.
