History of the Cave 

This object was mentioned for the first time in the middle of the 1st century AD in the work "History of nature" (Historia naturalis) published in 77 by Pliny the Elder, and later by other authors, for example Getaldić.

Systematic scientific research began only at the end of the 19th century, Groller (1889), Vavrović (1893), Katzer (1903), and others.

The most systematic scientific research of the cave was carried out by the Czech scientist (biologist, geographer, speleologist, paleontologist) Karel Absolon in the period from 1912 to 1914, when he discovered almost all the cave channels known today.

Topographic measurements and the first draft of the cave were made by Serbian geographer Mihajlo Rdaovanović (1929), while the hydrological cave was investigated by geomorphologist Sime Milojević (1938).

The complete plan with the use of a theodolite was made in 1958 by the Energoinvest company and the Speleological Association of Bosnia-Herzegovina Karst.

The latest research carried out since 2000 by the speleologists of SD Velebit from Zagreb resulted in the discovery of new channels and the most accurate topographical plan.

Since 2005, monitoring has been carried out, which includes continuous measurements of air and water temperature and pressure, relative air humidity, air flow speed and direction, and water level.

Underground habitats

The underground habitats of Vjetrenica consist of cave channels, cracks, underground waters and other underground living spaces. As living conditions, they are relatively stable, which means that the temperatures are constant (mostly the average annual temperatures of the area), as well as the air humidity, which is usually maximum. Underground habitats are quite dark and due to the lack of plants there is a constant relative scarcity of food.
