One of the earliest traces of human settlements near Stonehenge is Blick Mead.
It was built near a spring which had a very special property - rare algae caused stones taken from the water to turn bright pink when exposed to the sun.
It's possible that this granted the area a certain magical appeal, which could explain why settlers were attracted to the area in the first place.
It's thought that this initial Mesolithic settlement would have consisted of teepee-like structures.
The teepees were a circle of wooden posts, around 4m in diameter, likely covered in skins or bark, and with floor covered in moss.
Similar structures have been found at Star Carr, one of the most impressive Mesolithic settlements excavated in the UK.
More than 30,000 flints and animal bones were found at Blick Mead - suggesting that this was a place of significant gathering before the construction of Stonehenge.
Unfortunately nothing can be seen today.
