Stonehenge is an ancient monument situated about ten miles north of Salisbury in England. It was built about 4500 years ago, but by whom and for what purpose remains a mystery. The builders must have known of geometry. They may have been influenced by the Mycenaeans, whose architecture was similar. Some of the stones must have been brought from West Wales, over 135 miles away. These stones weigh more than fifty tons. They may have been brought on rafts and rollers. Experts say that it must have taken 1500 men more than five years to transport them. Stonehenge was probably built in three stages. First, settlers from continental Europe built a temple for sun worship. Later the «Beaker» people added the stone circles. Finally, people of the Wesse Culture transformed Stonehenge into an observatory. They could calculate the exact time of Midsummer and Midwinter and of equinoxes.
