Myra Falls (Lower Austria)
The Myra Falls ( or rarer: "Mirafälle"; always pronounced with a German "i") are located in a ravine in the municipality of Muggendorf in the Austrian federal state of Lower Austria (N.B. not to be confused with the Mira Falls ("Mirafall") 50 km further west in the "Ötschergräben"). The ravine has been cut by the "Myrabach", a small tributary of the Piesting. 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. Although the Myra is only  a few kilometres long, it used to power a large number of mills and sawmills in the Myra valley. In 1899 plans were laid for ""the exploitation of this waterfall for industrial purposes and thus the destruction of a natural beauty"". In 1912 Lord Oskar of Rosthorn ("Oskar Edler von Rosthorn") built a small pumped-storage power station at the Myra Falls, that was in operation until 1974/1975. The actual ravine with the falls is about 600 metres long; its height difference is 70 metres. The gorge runs from north to south and is protected as a natural monument. The  subsoil of the gorge is limestone. The Myrabach falls in several cascades through the gorge. At the upper and lower end the water is impounded into a small pond. A well-developed and popular hiking trail leads through the gorge. 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) and looked after them since then. There are two commemorative plaques at the entrance to the Myra Falls. The first recalls the ""opening up of the falls and the construction of the ascents by  the Pernitz Branch of the Ö. TC"". 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. Tourist Club and the "Enzian" Alpine Society on 8 June 1902."" There are restaurants at the top and bottom of the gorge. The entrance to the gorge may easily be reached on foot or by car (car park) and is located  about 300 metre north of the village of Muggendorf. The Myra ends shortly after the falls at Pernitz where it joins the Piesting. Postage stamp. 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.
