The large window that nature carved in the face of the Prisank mountain is the best-known in Slovenia. It is a staggering 80 metres tall and 40 metres wide.
Its tattered rock cliffs and the large mound of scree below indicate that sometime in history, the rock was punctured at a weak joint causing a landslide that, through rock-deterioration and weathering, grew to its present day size.
Which is the correct name, Prisank or Prisojnik? This is a dilemma that has been going on for more than a century. Both names mean the same in the Slovenian language and the name of the mountain indicates that its slopes are positioned to face the Sun.
