Mariazell is the most important pilgrimage site in Austria and also has great meaning for Catholics in the neighboring countries to its east. The object of veneration is a miracle-working image of the Virgin, carved in lime-tree wood. This was brought to the place in 1157, and is now enshrined in a chapel lavishly adorned with objects of silver and other costly materials. The large church of which the chapel forms part was erected in 1644 as an expansion of a smaller church built by Louis I, King of Hungary, after a victory over the Turks in 1363. In the vicinity of Mariazell is the pretty Alpine lake of Erlaufsee.
