Researchers find hidden remains of massive Neolithic stone monument, thought to have been hauled into position more than 4,500 years ago

Source: ‘Archaeology on steroids’: huge ritual arena discovered near Stonehenge

Archaeologists have discovered the remains of a massive stone monument buried under a thick, grassy bank only two miles from Stonehenge.

The hidden arrangement of up to 90 huge standing stones formed part of a C-shaped Neolithic arena that bordered a dry valley and faced directly towards the river Avon.

Researchers used ground-penetrating radar to image about 30 intact stones measuring up to 4.5m tall. The fragments of 60 more buried stones, or the massive foundation pits in which they stood, reveal the full extent of the monument.
