Dias Cross Memorial, Stone cross monument in Kwaaihoek, Eastern Cape, South Africa

The Dias Cross Memorial is a replica padrao cross set on the headland of Kwaaihoek, also called False Island, a high promontory jutting toward the sea beyond the sand dunes east of Boknes. The original cross raised there by Bartolomeu Dias on 12 March 1488 is kept at the University of the Witwatersrand in Johannesburg.

A Portuguese navigator placed the first stone cross at this location in 1488 during coastal exploration, marking a turning point in maritime travel. The original artifact was later discovered and is now secured for posterity.

The name Kwaaihoek, Afrikaans for "angry corner", refers to the exposed headland also called False Island where the replica padrao stands. The original stone cross, a padrao, was a Portuguese marker of claim and navigation; its remains are kept at the University of the Witwatersrand in Johannesburg, while the copy marks the spot on the headland.

The memorial is reached via a minor road from Alexandria, followed by a walk past sand dunes to the site. Visitors should wear sturdy footwear and prepare for open, windy terrain.

The original padrão cross no longer stands at Kwaaihoek: its remains are held at the University of the Witwatersrand in Johannesburg, while the cross on the headland is a replica. The headland itself is also called False Island, and the 1945 Government Gazette described the approach past Boknes and over the dunes to reach it.
