The remains of the roof of a house appear just above the sand at Sandwich Harbour in the Namib Nauclift Park, Namibia.
As one of the few places along the Namibian coastline that had perennial water, Sandwich became an important, if remote, stopover for both local Khoi people and European sailors from the 19th century onwards. A small settlement grew and Sandwich had numerous houses, a meat cannery and plentiful freshwater. Yet the sands of time and waves of change (both idioms in this case seem unusually appropriate) have drastically altered this wetland. The relentless winds have resized, reshaped and repositioned the dunes. The sea and the currents have eaten away the shore and deposited sand in other parts. It has to be one of the most dynamically changing ecosystems in the world.
