INAUGURATION
This highly significant work was inaugurated in the Sacré-Cœur chapel on December 8, 2013. It was then locked and sealed on December 28, 2014, closing day of the festivities for the 350th anniversary of the parish. In 2014, over 325,000 pilgrims walked through the Holy door.
JUBILÉ DE LA MISÉRICORDE (JUBILEE OF MERCY)
The Holy door was unsealed on December 8, 2015 by Cardinal Gérald Cyprien Lacroix, a few hours after the opening of the Holy door of Saint Peter’s Basilica in Rome, by the pope François, to mark the beginning of the Jubilee of Mercy. The opening ceremony of the Holy door took place on Saturday, December 12, 2015. Just over 200,000 people walked through it until it was sealed again on Sunday, November 13, 2016.
Unless Pope François decides otherwise, the door will remain closed until the next Jubilee planned for 2025.
