The exterior of the Constitutional Court, the highest court in South Africa. The doors of the Constitutional Court were first opened by President Nelson Mandela on 14 February 1995, but it occupied temporary accommodation elsewhere for a decade, until the new court was inaugurated at Constitution Hill on 21 March 2004 — Human Rights Day and 10 years after South Africa became a democracy.

The foyer of the Constitutional Court consists of concrete, timber, steel, stone and glass. The foyer’s mosaicked slanting columns represent trees, introducing the notion of ‘lekgotla’, which refers to the traditional African approach of conducting justice beneath a tree. (Photo: Shiraaz Mohamed)
