[2] She received several offers of marriage, which she refused because as her hagiographer Sabine Baring-Gould states, "she had chosen a bridegroom not of this world".

[3] Baring-Gould also states that Landrada "kept aloof from all worldly pleasures, and devoted whole days to prayer",[3] left her home and became an ascetic in the nearby forest, in the area of Munsterbilsen in northeastern Belgium.

[1][2][4] According to hagiographer Agnes Dunbar, Landrada experienced a vision that communicated the site of the convent: while praying in a lonely place, she saw "a cross of exquisite workmanship"[1] descend from heaven and impress itself on a stone, as if it were wax, nearby.

[1] Baring-Gould states that "according to popular legend",[3] Landrada appeared to Lambert in a dream after her death, telling him to bury her in "a spot which he would find designed by the apparition of a fiery cross",[3] which turned out to be in Wintershoven.

Three days later, Lambert ordered that a grave be dug for her at Wintershoven; by "angelic instrumentality",[5] her body, along with a marble sarcophagus, was transported there.
