Father Taylor of Carfin did not let up when his grotto opened in 1922. Over the next forty years the shrine was regularly expanded to include what Wikipedia describes as:

Taylor added many ‘holy statues and artifacts’ to the core imitation of Lourdes. He was a devotee of St Thérèse of Lisieux, a young French Carmelite nun who died of TB at the age of twenty-four and whose spiritual autobiography attracted a vast readership. She was beatified in 1923, canonised two years later and now has her own saint's day. Correctly anticipating her later popularity, Taylor had a statue of St Thérèse erected directly opposite that of the Virgin Mary and appointed her secondary patron of the grotto after Our Lady. If the expansion of the Carfin site can stand as a metaphor for the growth in Catholic numbers and confidence in the first half of the twentieth century, the Church's subsequent change of fortune can be symbolised by the fate of two extraordinary building projects: St Andrew's College, Bearsden and St Peter's Seminary, Cardross.
