Amazon.com Inc.’s planned new Africa headquarters in Cape Town is to draw demonstrations Wednesday as indigenous people protest its construction on a heritage site. A march will take place between a central museum and a statue of 17th-century colonialist Jan van Riebeeck in opposition to the project, which was announced in April as part of a 4 billion-rand ($291 million) mixed-use development on the outskirts of the South African parliamentary capital. While the City of Cape Town—which approved the site—has said the move will create thousands of jobs and give a boost to the Covid-19-ravaged economy, the plan quickly drew criticism from members of the Khoisan people, the original settlers on the land.
