Cave Gellert is part of the caves in the Gellért Hill. The cave is called "the cave of St. John" after the hermit who lived there, and is believed to use the natural thermal waters of the lake near the cave to heal the sick. It is likely that this is the same water that fall into the pool Gellert baths.

  In the 19th century the cave was a refuge for poor families, which, as I could, to equip a natural home. The cave entrance was closed. An illustration of this period of history you can see in the picture Mihai Myra, dated 1860 years of photos and Gyorgy Klёsha 1877.

  In 1920 a group of monks, inspired during a pilgrimage stone buildings of Lourdes in France, to equip the cave on his own and converted the entrance. From 1926 until 1951, the cave served as a chapel and even a monastery. During the Second World War here was located the field hospital of the German army. In 1945, the Red Army liberated Budapest. For six years, the cave continued to perform religious functions, but in 1951 in the framework of increased repression directed against the Catholic Church, the public security authorities raided the chapel. The cave was bricked up, the older brother Franz Weser sentenced to death, the monks - to prison terms of up to ten years.

  The chapel was reopened August 27, 1989 - thick concrete wall, closes the entrance, was destroyed. By 1992, the chapel was restored and put in order. Currently, services are held in the cave, despite the fact that it is a tourist attraction.
