An overhead view into a circular ditch surrounding a grassy area with standing stones, fire pits, and several people.

A ditch 60 m in diameter, 5 m across and about a metre deep, with steep sides and a flat base. The chalk taken from it piled up inside, leaving a gap of about 3 m and creating a bank over 2 m high Both bank and ditch had a gap facing exactly due east, towards the equinox sunrise on 21 March and 21 September. The location of the henge also meant that this line also crossed the Ivel springs. In the centre of the entranceway was a line of three irregularly shaped pits that were deliberately backfilled with clay. Inside the bank, people were setting small fires on which they burnt polished stone axes among other things, and smashed pottery. See more
