The congregation was originally founded in Paris but was obliged to find a new Mother House due to French legislation passed in 1901.

The nuns at the London convent practice the Perpetual Adoration of the Blessed Sacrament and maintain a shrine dedicated to the Catholic martyrs of the English Reformation.

A Frenchwoman, Adèle Garnier, in religion, Mother Marie de Saint-Pierre, established the community in Montmartre (Mount of the Martyr), Paris in 1898.

[1] In 1901 the French legislature passed the Waldeck-Rousseau Law of Associations which placed severe restrictions on religious bodies such as monasteries and convents and caused many of them to leave France.

Mother Garnier relocated the congregation to London in 1903, to what became the Tyburn Convent in Bayswater Road, near Marble Arch.

Mystical experiences in the original congregation in France indicated that Adoration was needed to atone for sacrilege and blasphemy committed by priests and lay people against the Blessed Sacrament.

Perpetually professed sisters wear the black veil, medal, ring, and white choir cowl.
