Some of them are still standing at the beginning of the 21st century, and are a good example of adaptation to the geographic environ- ment, and a part of the historical heritage. Following a short overview of the different Mediterranean countries, this work pays special attention to the pre- sent use of caves as dwelling spaces in Italy, and particularly in Spain where the caves are currently in an interest- ing process of renovation to meet the needs of the present population. This process is helping to boost the local economy, and it is funded by both private and public sources in several towns in Andalusia (Spain).
