A Glimpse into Thesen Island’s History✍
Thesen Island is steeped in the captivating history of the Southern Cape, nestled amidst the serene waters of one of South Africa’s most ecologically diverse estuaries. The island’s origins trace back to the ancient San people, or Bushmen, who were believed to be the earliest inhabitants of the area. As settlers arrived, drawn by the abundance of indigenous forests that harboured herds of the renowned Knysna elephant, the island came to be known as Paarden Island, meaning “Horse Island.”
The island’s modern-day name, Thesen, has its roots in Norway. In 1869, Arndt Leonard Thesen, a prominent timber merchant from Stavanger, embarked on a journey to New Zealand with his family. However, their ship encountered difficulties near Cape Town, prompting Arndt Thesen to make South Africa their new home. Settling in the picturesque town of Knysna, surrounded by pristine forests, the Thesen family established a timber trading company.
Fast forward several decades to 1991, Dr Chris Mulder, an environmental engineer with a doctorate in environmental design, proposed a visionary redevelopment plan for Thesen Island as a distinctive residential marina. The project faced rigorous scrutiny due to the estuary’s ecological significance and its popularity as a tourist attraction. After eight years of meticulous research and planning, Dr Mulder and his team received approval in December 1998, albeit with over one hundred strict and complex conditions.
The journey from the initial concept to final approval spanned a decade and involved twenty-five alterations to the master plan, demonstrating the commitment to maintaining ecological, architectural, and social integrity. Thesen Island’s history is a testament to the resilience of nature and the transformative power of human vision. Today, it stands as a testament to sustainable development, harmoniously blending modern living with the preservation of its unique natural surroundings.
