Vela spila is located on the southern slope of the Pinski rat mountain, 130 m behind the Kale bay in Vela Luka and is one of the most important prehistoric archaeological sites in Europe.
The archaeological finds that were found provide evidence of the population and all forms of life of some prehistoric groups of people who used the cave as an everyday habitat and as a burial place for their dead. Thousands of found fragments of ceramics, entire vessels and other objects represent a first-class importance. On them pages of cultural, social, emotional and business relationships of the users of the Vile spila with near and wide areas of the Adriatic and the Mediterranean are written.
Judging by the latest research, it can be concluded that the cave has been continuously inhabited since the early Stone Age, that is, around 20,000 BC, and some finds indicate that there was even a presence of people in earlier eras - bronze and Iron Age - took place It was also used by Greeks, Romans, Byzantines and many others to this day.
The cave entrance is 1 to 10 meters wide, four meters high and faces south, with a wonderful view of the wide bay, the nutritious moorland, the islands of Ošijak, Kamenjak and Proizd, more distant islands of Vis, Sušac, Sv. Andrija, Biševo and the open sea.
