This is the corridor of B Block in the Robben Island maximum security prison.
We took the boat out from Capetown and did the prison tour.
The cell where Nelson Mandela spent the major part of his 27 years in prison is second from the end on the left of the picture. It is impossible to stand in the cell and not feel the presence of something bigger than us all.
Tours of the prison are led by ex-inmates and the man who took us gave us a very vivid sense of what went on in this place. He spoke most powerfully of the political meetings that were held and the discussions during the drafting of documents that led to the current South African Constitution and to the Truth and Reconciliation Commission. The documents, signed by Mandela and others, are on display.
To me the prison seemed to represent both a low and a high point in African history.
