It was constructed at the behest of Sir Rufane Donkin (acting governor of the Cape 1820–1821) in memory of his wife Elizabeth Donkin née Markam, who died in India in 1818.
The pyramid measures 10 metres (33 ft) high and is constructed of local stone.
[2] Sir Rufane Donkin named the town Port Elizabeth after his late wife and declared that the land around the pyramid would be a reserve "open to all in perpetuity".
A lighthouse (built in 1861) stands next to the pyramid, serving the harbour below.
[4] The silhouette of the Donkin memorial and lighthouse has been used as a symbol to represent the town of Port Elizabeth, notably in the logo of the German Club, Port Elizabeth.
