After the destruction of the Collegiate Church of St. Peter, which had been badly damaged during the Austrian siege of 1792 before being demolished in the French Revolution, the statue largely fell into oblivion. It was bought by a sexton, Alain Gambier, who placed it in the Church of St. Catherine, where it remained between 1797 and 1802. It was not until 1842 that Charles Bernard, parish priest of the Church of St. Catherine, restored the cult of Our Lady of the Treille and tried to strengthen it again: he instituted the month of Mary, patron saint of Lille, and had the statue placed in the Chapel of the Blessed Virgin of St. Catherine's Church. The celebration in great pomp of the secular jubilee of the first miracles of Our Lady of the Treille, in 1854 constituted a decisive step in this restoration work. The restoration project is also believed to have been marked by providence, due to the unexpected acquisition of the land on which the new church in honor of the Lady of the Treille would be built, making it possible to lay the church's foundation stone before the end of the jubilee celebration.
