World Heritage sites are different places, monuments, and artwork that have been considered to be of great value to humanity in one form or another. UNESCO tries to protect these sites so future generations can see our natural heritage.
The rock drawings in Valcamonica have more than 140,000 carvings that date back to over 8,000 years, representing a group of people that no longer exists. The figures of agriculture, dance, war, etc. help form ideas of how they once lived and thought, and further contribute to the fields studying their history and sociology.
The trulli of Alberobello are pyramid shaped dwellings that were formed from limestone boulders found in the surrounding fields. This sit represents the very beginning of a construction technique that is still used in today's modern buildings in this area.
