Cultural Landscape
Kakadu is a living cultural landscape with over 5,000 Aboriginal rock art sites. These include big paintings, rock art styles and paintings from the 17th century, 19th century and even earlier.
Important rock art can be found in rock shelters and at places like Nourlangie Rock, where ancient stories—sometimes called magic-paintings—show daily life, spirituality and the connection between people and the land.
The area has been a mining camp, a mining boom and a land claim site. Today, it’s all about balancing conservation and cultural heritage with the ongoing debate about mining and the protection of rich uranium mines and uranium deposits.
