The Myra, as the stream is also known, rises at the foot of the Unterberg from the Myralucke, a spring steeped in legend, that is fed by an underground lake.
In 1899 plans were laid for "the exploitation of this waterfall for industrial purposes and thus the destruction of a natural beauty".
It was built in 1885 by the Pernitz branch of the Austrian Tourist Club (Österreichischer Touristenklub), with 19 bridges and 8 ascents (opened: 9 August 1885)[4] and looked after them since then.
The second panel is dedicated "to the memory of the visit to the Myra Falls on 19 September 1801 by His Majesty the Roman-German Emperor, Francis II, Her Majesty Empress Maria Theresa, and by Their Imperial Highnesses, the Crown Prince Ferdinand Karl Leopold Joseph and Archduchess Maria Ludoica, donated by Aust.
On 7 December 1977 the Österreichische Post brought out a definitive stamp on this subject in their Austrian landscape series to the value of 20.00 shillings.
