'Archaeology on steroids': huge ritual arena discovered near Stonehenge

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

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.
