To me it would seem totally logical to build a lighthouse as high above sea level as possible. As we saw with the old Cape Point lighthouse, there is such a thing as too high, particularly when you’re building in an area that is prone to heavy mist and fog. The most notable shipping casualty that occurred after construction of the old Cape Point light was that of the Lusitania, wrecked on Bellows Rock in 1911. A new lighthouse was planned, along with a light at Slangkoppunt in Kommetjie, to replace the old light at Cape Point.
The new lighthouse was built on a 15 metre high pinnacle of rock called Diaz Point, which was dynamited to form a flat platform upon which the lighthouse would be built. Building materials were hauled by oxen from Simon’s Town, and transported by tram down a track on the cliffs. Most of the way the gradient of this tram track was 1 in 4; for a short stretch it was 1 in 2. This is incredibly steep. At the end of the tram track, the building materials were lowered by crane onto a ledge. Building sand was excavated from a cave at the bottom of the cliff, and carried up to the platform on which construction took place. Water was brought close to the building site by trolley, and piped down onto the location.
Like the old lighthouse, the new lighthouse is nine metres high, but instead of cast iron, it is constructed from masonry and the tower is square. The lantern house on top is white. The new lighthouse’s elevation is 87 metres above sea level, giving it a range of visibility of 32 nautical miles. The fully automatic light flashes three times every 30 seconds, and there is a subsidiary red light in the base of the lighthouse facing towards Anvil and Bellows Rock. This light is only visible from the sea, if you go around Cape Point to the western side of Cape Point.
On 11 March 1919 the new lighthouse was commissioned (put into service). The view from this lighthouse covers a full 353 degrees, with seven degrees obscured by Da Gama Peak behind it. It was manned for a time, but is now automated.
The public is not allowed to visit the new lighthouse, or even to get particularly close to it. It can be viewed from a viewpoint at the end of the Lighthouse Keeper’s Trail, a highly recommended short walk from the old lighthouse at Cape Point. Along the way you will see the remains of World War II bunkers and a radar station, and you will traverse the most fantastically narrow ridge of rock (in perfect safety). The wind is likely to be extremely strong, whatever time of year you go – dress accordingly. Also note that the walk does not take nearly as long as is suggested by the signage at the start. It is approximately one kilometre each way.
As usual, everything I know about this lighthouse that I didn’t learn by looking at it (i.e. most everything), is thanks to Gerald Hoberman’s wonderful Lighthouses of South Africa book.
