Stonehenge is considered one of the most mystical places in the world and a must-visit while in the United Kingdom. Located in Wiltshire county in South West England, it belongs to the list of UNESCO World Heritage Sites since 1986.
Some archeologists believe that Stonehenge was built between 3000 BC and 2000 BC as a simple earthwork enclosure where prehistoric people buried their cremated loved ones. The stone circle was placed in the center during the Neolithic period (around 2500 BC)
According to some sources, Stonehenge was constructed in four phases in different periods of time: The first one was probably built around 3100 BC, the second one (and the most dramatic) was constructed around 2150 BC and the third one, around 2000 BC, and the last one, around 1500 BC. Two different kinds of stones were used to build the monument, one of which was Sarsen stones, which weighed 25 tons.
Despite the nonstop research, no one knows for sure what Stonehenge was built for. Theories about the use of the monument include: a place for burial, a place for healing, a celestial observatory and more.
