Pečinka Cave is located in the vicinity of the village of Lokvica, which was totally destroyed during the war. It is a 150 metres-long slanting cave with a vertical drop of 22 metres. It is of natural origin (70 % of the present cave) but continues into a man made tunnel, leading up to the top of Pečina hill (308 m). The cave is rich in calcareous sinter, but its formations are rather damaged. It is also interesting for the archaeologists, since during pilot excavations at the beginning of the 20th century numerous fragments of prehistoric pottery and human bones were found.
In order to make the best possible use of natural caves and abysses, the Austro-Hungarian Army formed a speleological construction detachment at the Seventh Corps, which numbered 500 men. It was headed by the speleologist and engineer, First Lieutenant Alois Peter Bock. From 10 March till 15 April 1917 the Slovenian natural scientist and speleologist Pavel Kunaver (1889–1988) was also active in this Detachment. They researched and arranged several hundreds of caves, of which many were tailored for the military’s needs. The construction works were mainly carried out by Russian POWs.
During World War I, Pečinka Cave served as a shelter for soldiers. It was first in the hands of the Austro-Hungarian Army, but in November 1916, during the Ninth Isonzo Battle, it was occupied by the Italian troops and controlled until the Austro-Hungarian breakthrough in the Twelfth Isonzo Battle of October 1917. The cave was furnished with bunks for soldiers and cabins for officers. On the top of Pečina hill (308 m) there was an observation post where a searchlight was located. Due to its strategic position the hill was named the Eye of the Kras. Nowadays, Pečinka Cave is set up for visitors.
