The Dog fence
1885.This fence was built only on one purpose: to stop dingoes (Australia’s wild dogs)
from killing sheep.
It is one of the longest structures on the planet, and the world's longest fence. it’s 3,307
miles long. That makes about 5,320 km. That is about two and a half times longer than the
Great Wall of China. The fence starts near the coast of Great Australian Bight and ends up
in the eastern part of Queensland in the Bunya Mountains, not far from the Pacific Ocean.
At the time, it was the longest man-made structure in the world. It was only partly
successful; Dingoes can still be found in parts of the southern states to this day, but
although the fence helped to reduce losses of sheep.
The fence is 2 meters high and it extends about 30 cm underground to keep the dingoes
from digging under it. There is a gate approximately every 19 km s.
