The island of Korcula and the peninsula of Peljesac were inhabited even in the Neolithic Age, i.e. six to eight thousand years ago.
There are numerous archeological findings from that time, ranging form the first settlements, caves, tumili, and old stone buildings (gradine) to the earliest tools such as stone axes, pieces of ceramics and flint knives. The most important localities dating from that time are: Vela Spilja (Big Cave) near Vela Luka, Gudnja and Spila on Peljesac, and Jakasova spilja (Jakas’s Cave) near Zrnovo. There are also numerous tumuli and stone buildings, the earliest types of fortified settlements, using natural unworked stone; they are most often situated on peaks and hills, providing a good view and difficult access for the possible invader. It would appear that the whole territory of Korcula and Peljesac was parceled out according to zones of interest.
