The pilgrimage church Maria Schnee from the year 1660 is worth a trip in any weather.
Kalkstein, a hamlet of Innervillgraten, is located about 4 kilometres from the village of Innervillgraten. The pilgrimage church Maria Schnee was consecrated in 1875. Its exterior is, apart from a circumferential pedestal, without special structure. The registry is on the east side. The interior of the neo-Gothic building is characterised by a simple star-ribbed vault with pointed choir arch.
The village of Kalkstein has also become famous for being the shooting location for the film "Gewitter im Mai" by Ganghofer.
