Josef Stroff and Matthias Leisser donated a beautiful Maria Lourdes statue in 1885. In 1908, Pastor Karl Rasperger, actively supported by Mayor Georg Leisser, had the Maria Lourdes Grotto built at the beginning of the Stagel Gorge. An ancient pagan sacrificial stone was installed, on which the statue of Mary stands. The grotto was consecrated on May 16, 1908.
