The Cave Church of Gellért Hill was founded in 1924 following a pilgrimage of Pauline monks to Lourdes. The chapel was consecrated on Whit Sunday 1926, and Pauline monks performed their duties here for 17 years. At midnight on Easter Monday 1951, the Hungarian secret police (IVH) broke into the chapel, arresting the entire order. The superior, Ferenc Vezér was condemned to death, the others condemned to minimum five year prison sentences, and the chapel blocked up with a 2.25m-thick concrete wall. It was not until August 27, 1989, that the chapel was reopened and the revived Pauline Order returned, although the demolition of the concrete wall was not finished until 1992.
