Letterklip
South Africa
The Letterklip, Afrikaans for "lettered rock", is a provincial heritage site in Namaqualand in the Northern Cape province of South Africa. The unique rock formation was fortified by dry stone walling; it was occupied from 1901 to 1902 by British forces during the Anglo-Boer War. Various regimental badges and officers' names are engraved in the rockface.
