Protesters gathered at the front gates of the estate before walking up Prince of Wales Avenue to Parliament Buildings.
They stood there in silence, with heads bowed and holding lights, for six minutes, to represent the six counties in Northern Ireland.
DUP leader Arlene Foster and UUP leader Robin Swann were among the crowd.
An academic counting those who took part in the walk to Parliament Buildings estimated numbers at 4,000, while later, event organisers said there were in excess of 20,000 people at the demonstration.
In July, MPs passed the Northern Ireland (Executive Formation) Act, which contained a provision placing a duty on the Government to regulate to provide for access to abortion in Northern Ireland.
