Stonehenge: The Discovery with Dan Snow will premiere at 9pm on Sunday, March 31 on Channel 5 and My5.

The programme will follow Dan as he attempts to piece together the history of the stone circle and reveal modern discoveries that are moving the world closer to uncovering its mysteries.

Along his journey, Dan visits the Wiltshire Museum in Devizes to examine the Bush Barrow Chieftain and his gold lozenge found by William Cunnington in 1808 and goes among the stones with skyscape archaeologist Fabio Parracho Silva of Bournemouth University to measure the astronomical alignments of Stonehenge.
