Within each of the regions we have identified individual sites. A site is a locus of human activity. The evidence collected by the Survey suggests different site functions, such as settlement; religious (cave sanctuary, temple, church); economic (bee-keeping, shepherding). We have recorded over 300 sites, ranging in date from ca 3300 B.C. to A.D. 1898, at altitudes from sea level to 2454 metres above sea level.
