The cave Škocjanske jame has a long history of which the relatively short period between the two World Wars is the subject of this book. The area had just been transferred from Austria to Italy. Most of the cave had been explored before 1914 so the objective in the 1920s and 1930s was mainly to develop it as a tourist cave. Visitors had been accepted earlier but the emphasis now shifted to developing the tourist route through the cave, with new bridges and pathways as well as a new tunnel to the surface. The need for all arrangements to be formalized under Italian law caused problems and the re-opening of the cave to the public was delayed until 1923. Besides this development work, some exploration took place, new surveys were made and there were scientific studies. A little-know fatal accident is reported. Throughout the whole period the personalities of the individual guides, explorers and managers lead to a very human story as well as an exciting one. What helps to make this book so significant is the immense input from Italian archives, archivists and historians.
