The Justice For Magdalenes Research group has said that a huge amount of work needs to be done to identify where all of the women who died in Magdalene laundries are buried.
Co-founder Clare McGettrick said at least 1,600 women died in these institutions but it is still not known where many are buried.
She was speaking at Glasnevin Cemetery today, one of several locations where flowers were laid on Magdalene graves.
Events were also held in Cork, Galway, Limerick, Waterford and New Ross.
Survivors, as well as children of women who died in Magdalene laundries, spoke at today’s events.
They called for permanent memorials and sensitive development on former laundry sites.
