Stonehenge 101 . .

A few things I learned . .

Stonehenge was built between 3100 – 1100 BCE.

The circle was built to align with the midsummer sunrise, the midwinter sunset, and with the most southerly rising and northerly setting of the moon.

The formation and construction of Stonehenge demonstrates a great understanding in math and geometry.

The builders used two types of stones used in its construction: the bluestones which weighed as much as four tons and were brought from 240 miles away) and the Sarsen stones (averaging about eighteen feet in height and twenty-five tons in weight).

Experts have also estimated that the construction of Stonehenge required more than thirty million hours of labor.

There are more than nine hundred stone rings exist in the British Isles but Stonehenge is the most well known. I also visited one in Avebury - it had a much larger radius.

The rock formations in Britain predate eastern Mediterranean, Egyptian, Mycenaean and Greek cultures.

Something I didn't learn . .

If aliens built it.
