A window into which you could fit the Ljubljana Skyscraper!
Beside the Heathen Maiden, Prisank offers another natural attraction. The front window on the upper edge of the Prisank northern wall is the most well-known window in the Julian Alps and one of the largest natural orifices in Slovenia. It is around 80 m high and around 40 m wide.
It was formed by a collapse, which expanded into the current orifice due to weathering.
The window can even be seen from the road. However, if you go from Vršič along the ridge towards the top of the Prisank Mountain, the path leads you past the window and you can even look through it into the valley.
