Lore Lindu National Park receives international technical assistance and has been declared by UNESCO as a Biosphere Reserve in 1977.
Besides the riches of its natural resources, this Park also has some impressive groups of megaliths which are among the best megalithic monuments in Indonesia. Various archaeological studies have found that the stone forms date from 3,000 BC to 1,300 AD.
It is presumed that the statues were once the objects of worship. The statues are made of gray stone that is not found in the area. Some represent people but though their limbs and genitals can be made out, their facial features have worn away over time. Although most of the stone forms are between 150 centimeters and 250 cm tall, the tallest statue is four meters high. Natives have fenced off the statues to protect them from vandals. They believe the statues once had special powers, which have waned since the arrival of Christianity in the province.
