Wakefield Council leader Peter Box unveiled a commemorative stone honouring Nelson Mandela on Friday.
The memorial stone is a key feature in Mandela Garden in Crown Court Yard, off Wood Street.
The decision to honour the former South African leader, who died in December last year, was made at a full council meeting.
Coun Box said: “Nelson Mandela was a remarkable man whose determination to win freedom and democracy for all the people of South Africa was truly awe-inspiring.
“Freedom is hard won but easily lost and it is right we honour his memory.
“This commemorative stone in Crown Court Yard is a fitting way to remember all that Nelson Mandela achieved.”
