St. Stephen's – The Living Cathedral

St. Stephen’s Cathedral ranks amongst Austria‘s most famous cultural monuments. Yet, one would not think of that Cathedral being one of the most astonishing natural areas in Austria.Georg Riha and his team have explored the Cathedral from its foundations to the top of its 136 meter spire and discovered a true botanical and zoological garden: wild animals, exotic butterflies, kestrels, moss, lichen and even trees.
