Because they are in such close proximity to one another, I have often considered this lighthouse and the adjacent pyramid as being contemporary structures. Nothing could be further from the truth. This blog, largely based on the 1986 thesis by Jon Inggs, provides the historical detail from the conceptualisation to the erection of the Donkin Lighthouse.
The combination of the pyramid and the lighthouse symbolises Port Elizabeth and is so integral to Port Elizabeth that it could be considered as its trademark. The unique combination very nearly never came into existence as the Harbour Master, Mr H.G. Simpson favoured dismantling the pyramid and using its stone to construct the lighthouse.
