Stonehenge is made up of 2 circular settings of large standing stones, the inner
circles stones are 26 feet high and the outer circles stones are 10 feet high.
There are two types of stones used in the construction of Stonehenge. The large
outer circle is made of Sarsen which is sedimentary Sandstone and the inner circle
is made of Bluestone which is a blend of Basalt and Gabbro.
It is believed Stonehenge was constructed anywhere between 3000BC and
2000BC.
The Stones are said to have been quarried and shaped by workers and then
transported to the site. How they were transported still remains a mystery. The
stones have been weathered throughout the years by rain and wind.
The approximate age of Stonehenge is 5000 years old.
Many historians believe several different types of tribes of people built
Stonehenge between 3000BC and 2000BC, each building a different phase of it’s
construction. Many people believe the first stage was built by the people of the
Neolithic Period.

SPRINGS RUN DOWN THE ROCKS DURING WETTER MONTHS WHICH HAS
FORMED THE SHAPE OF WAVE ROCK. THE COLOURS IN THE ROCK HAVE BEEN
CAUSED DUE TO CHEMICAL REACTIONS.
