Also known as Twyfelfontein, ǀUi-ǁAis was the first place in the country to be named a UNESCO World Heritage Site in 2007.
It has been inhabited for more than 6,000 years, first by hunter-gatherers and later by Khoekhoe herders who used it as a place of worship.
Some 2,500 rock carvings were left behind, including at Twyfelfontein Lodge, where we stayed. We found the engravings a short walk from the lodge's reception nestled between large boulders. They were well preserved, standing out on the rock face in the hot Namibian sunlight.
