Speaking at the 48th anniversary gala dinner to honour the Rivonia Trialists in Sandton, Mashatile said the story of the farm - which was used as a meeting place and a hide-out for senior ANC and SACP leaders in 1960 - had to be told "again, again and again", The Times reported on Tuesday.
The farm was bought by MK High Command and the SA Communist Party, and was to be used as a meeting place and a hideout for banned activists from police.
However, on July 11, 1963, police raided the farm and found the men studying "Operation Mayibuye" - an MK proposal for guerrilla warfare and revolution.
Struggle heroes including Walter Sisulu, Govan Mbeki, Rusty Bernstein, Ahmed Kathrada, Denis Goldberg, James Kantor, Andrew Mlangeni, Raymond Mhlaba, Nelson Mandela and Elias Motsoaledi were all arrested.
Arthur Goldreich and Harold Wolpe escaped before going on trial.
Zuma, who also attended the dinner, said in his keynote address: "We believe that by preserving this heritage [Liliesleaf farm] we are contributing to the ongoing process of national healing and the building of a more cohesive society.
"We will therefore continue to ensure that the story of [the farm] is told in full for the benefit of current and future generations," Zuma said.
