Split granite rock in the Tasman Bay off the northern coast of South Island, New Zealand.
This unusual formation, situated between Kaiteriteri and Marahau, attracts visitors often by boat or kayak.
However, exactly how the rock split in two halves is not known but has attracted mythological explanations.
One Maori legend describes how two gods fought over the large boulder, and finally in order to settle the dispute, they used their powers to break the rock into two perfect halves.
Geologists meanwhile have suggested the split was caused during an ice age when expanding ice caused by water caught in a crack pushed the two sides apart.
