Stonehenge

Stonehenge is one of the most famous and baffling prehistoric megaliths in the world. The circular monument consists of an outer ring of vertical stones and an inner circle of smaller stones. Built between 3,000 and 1,520 BC, Stonehenge's builders left no records, making room for speculation that it may have been an astronomical device used to predict eclipses, or a healing centre for the sick and injured, or even a landing pad for space aliens. The mystery surrounding the structures, which would have taken enormous effort and special tools to build, is part of its attraction. 

On a visit to Stonehenge, you can walk around it for a 360-degree perspective and pay a fee to enter the inner circle. The Neolithic Houses at the site offer a feel for life during the time Stonehenge was built. Stonehenge exhibitions explain the history of the monument via audiovisual aids. If you're visiting around the time of the summer solstice, you can join thousands of people at Stonehenge to witness the longest day of the year. Stonehenge is an open-air site and the weather can be unpredictable, so prepare accordingly.
