In 1743 Swellendam was declared a magisterial district, the third oldest in South Africa, and was named after Governor Hendrik Swellengrebel, the first South African born Governor, and his wife, Helena Ten Damme. This outlying settlement soon became a gateway to the interior, and was visited by many famous explorers and travellers including François Le Vaillant (1781), Lady Anne Barnard (1798), William John Burchell (1815) and Thomas William Bowler (1860).
