To the left of the Poelberg meeting centre, a small staircase leads to this grotto, which is classically built based on the original in Lourdes, France, where Mary is said to have appeared several times in 1858 to the 11-year-old shepherd girl Bernadette van Soubirous.

The Mariagrot in De Ginste was built in 1920 as thanks for Oostrozebeke being spared from war destruction during the First World War. The cave was built with rubble from destroyed buildings in Zonnebeke. The cave was rebuilt thirty meters deeper on the enlarged site in April 1946. In the month of May, many pilgrims visit the Ginstegrot. However, things were not always so Catholic in De Ginste for a long time. The neighborhood was known as a refuge for rebels. People regularly gathered there to perform black masses. Pastor Bracke presided over these services and was later removed from his position for this.
