A low gateway made of metal and wood will be installed in the interior part of the cave, as well as instructional signs on the history and the findings of the cave. There will be no need for electric lighting installations as the large opening of the cave provides natural light. The cost of operations is estimated to reach € 200,000.
Franchthi Cave is unique in having an essentially unbroken series of deposits spanning the period from 20,000 B.C. (and probably even earlier) down to 3000 B.C, by far the longest recorded continuous occupational sequence from any one site in Greece. The most significant discovery in Franchthi Cave is a skeleton of a young man, dating about 10,000-8,000 years ago.
