Harbour expansion and reclamation
The discovery of gold and diamonds in South Africa meant that the first section of harbour, the Alfred Basin, was not large enough to accommodate the increased number of ships, and the Victoria Basin was built. The construction of these two harbour basins took place between 1860 and 1920, and this area of the harbour still has an array of outstanding heritage buildings from this era.
In 1938 work was started to reclaim land between the city centre and the harbour, most notably the new Duncan Dock. The Foreshore (230 hectares) made city expansion possible. In the early 20th century, South Africa depended mainly on imports for many basic articles in daily use, which explains the importance of the harbour to the people who lived here.
