A total of 130 political prisoners were hanged between 1960 and 1990 by the apartheid government, at the then Pretoria Maximum Prison, now Kgoši Mampuru Correctional Centre.
They were all buried in unmarked graves in the capital and at least 83 of them have been exhumed since December last year.
PAC General Secretary Narius Moloto says the blood of those heroes has nourished the democracy South Africans are enjoying today.
Moloto says their members will be given dignified burials.
