A short ways east of Canterbury he helped found and dedicate to St Martin of Tours the first Christian Anglo-Saxon church in England, St Martin's, still serving as the oldest church in the English-speaking world.

[2] He is believed to have died in the late 590s, soon after the arrival of Augustine with the Gregorian mission, but Bede fails to mention him in any detail.

He was regarded locally as a saint, and Goscelin recounts the story of a miracle he performed to help the 11th-century artist and abbot Spearhafoc, who in thanks adorned his tomb, with "statues of enormous size and beauty" of the saint and Bertha.

According to Goscelin, while Spearhafoc was working on metal figures at St Augustine's Abbey in Canterbury, he lost a valuable ring given him by Edward's queen, and Godwin's daughter, Edith of Wessex, presumably as materials to use in his project.

[4] Also according to Goscelin and William of Malmesbury, Liudhard "was especially good at speedily responding to appeals for rain", for which purpose his remains would be carried in procession to the fields.
