Archaeologists unearth Neolithic henge at Stonehenge

Archaeologists have discovered a second henge at Stonehenge, described as the most exciting find there in 50 years.

The circular ditch surrounding a smaller circle of deep pits about a metre (3ft) wide has been unearthed at the world-famous site in Wiltshire.

Archaeologists conducting a multi-million pound study believe timber posts were in the pits.
