Until 1889 Karmel Mayerling served as hunting lodge and was known as Schloss Mayerling. On 30th January 1889 the Mayerling incident took place in this lodge. The heir to the Austrian throne Rudolf and his lover Baroness Mary Vetsera died under mysterious circumstances.
After their decease the building has been turned into a monastery (Karmel Mayerling). The chapel depicted above has been erected at the place where the two were found dead.
