Woodhenge is a curious Neolithic monument, two miles north-east of Stonehenge. The site was believed to have consisted of a central burial mound – where a sacrified child was laid to rest – and then six concentric rings of enormous wooden posts, believed to have been up to 7.5m high. The posts are now replaced with concrete pillars and there are 168 in total.

Woodhenge: It's been speculated that this was the site where a child was sacrificed, thousands of years ago

There are puzzling similarities with the more famous Stonehenge. Both have entrances that line up with the midsummer sunrise and the diameters of the timber circles are comparable. Why? Archaeologists can't say, for sure. So answers on a postcard, please...
