Its most recognizable features are a ruined Norman church built within a neolithic henge monument.

Aerial photographs reveal a large number of ploughed-out barrows in the immediate vicinity.

The earliest parts of the building are the 12th-century chancel and nave and there are 15th and 18th century additions and alterations.

[2] Early Christian activity at Knowlton is indicated by a mid-to-late Anglo-Saxon inhumation cemetery which was discovered to the east of Church Henge in 1958.

This land paid geld, was enough for one plough with one slave and one bordar, a mill paying 12s6d, and was worth 25s.
