Seal Point Lighthouse has watched over the Cape St Francis coastline for almost 150 years. Rising above the rocks, it remains one of the region’s most recognisable landmarks.
Construction began in November 1875, and the lighthouse became operational on 4 July 1878. Since then, its powerful beam has helped ships navigate this exposed section of the Eastern Cape coast.
South Africa’s Tallest Masonry Lighthouse
Standing 27.75 metres high, Seal Point Lighthouse is South Africa’s tallest masonry lighthouse. Its circular white tower supports the lantern room above the surrounding buildings.
The lighthouse has a focal height of approximately 36 metres above sea level. Its revolving light produces a white flash every five seconds. In clear conditions, ships can see the beam from around 28 nautical miles away.
Although the building dates back to the 19th century, it remains operational. Its navigation equipment has changed considerably over the years. However, its purpose remains the same.
Building At The Edge Of The Ocean
Constructing the lighthouse required an enormous effort. Builders had to transport materials from Humansdorp by ox wagon across difficult terrain.
Each journey reportedly took about two weeks. The wagons crossed rivers, valleys and rough countryside before reaching Cape St Francis. There were no modern roads, heavy vehicles or construction cranes to make the job easier.
The final cost of the lighthouse was recorded as £20,000, a substantial amount at the time.
A Cape St Francis Landmark
Seal Point Lighthouse received National Monument status in 1984. Today, it is recognised as a Provincial Heritage Site and remains an important part of South Africa’s maritime history.
However, the lighthouse is only part of the attraction. The surrounding coastline offers walking and cycling trails, rock pools, birdlife and sweeping ocean views.
The area also carries the unmistakable character of Cape St Francis. Waves break across the point, seabirds move along the shoreline, and the lighthouse continues to dominate the landscape.
Nearly 150 years after its light first shone, Seal Point Lighthouse remains both a working navigation aid and an enduring symbol of Cape St Francis.
