Lidwina died in 1434 and was buried in a marble tomb in the chapel of the parish church of Schiedhams which became a place of pilgrimage. Thomas à Kempis's publication caused an increase in veneration. In 1615 her relics were taken to Brussels, but in 1871 they were returned to Schiedam. On 14 March 1890, Pope Leo XIII officially canonized Lidwina. She is the patron saint of ice skaters and the chronically ill, as well as of the town of Schiedam. Her feast day occurs on 18 March, 14 April, or 14 June, depending on region and tradition.
