Palach was initially interred in Olšany Cemetery. As his gravesite was growing into a national shrine, the Czechoslovak secret police (StB) set out to destroy any memory of Palach's deed and exhumed his remains on the night of 25 October 1973. His body was then cremated and sent to his mother in Palach's native town of Všetaty while an anonymous old woman from a rest home was laid in the grave. Palach's mother was not allowed to deposit the urn in the local cemetery until 1974. On 25 October 1990 the urn was officially returned to its initial site in Prague.
