Four thousand years separate the main late Neolithic earthwork at Knowlton and the Norman church that stands at its centre. The earthwork itself is just one part of a landscape which is one of the great Neolithic and Bronze Age ceremonial complexes in southern England.
The church was built in the 12th century and was in use until the 17th century, serving a now vanished hamlet by the riverside. Its Norman origins are evident from the plain round arch leading into the east end or chancel, and from the round-headed arches of the arcade dividing the nave from the north aisle. The south door also looks Norman.
The tower at the west end is 15th century, and is built of flint with bands of stone; the line of the church roof is clearly visible on its eastern face. At the east end of the north aisle there appears to have been a lady chapel.
Whatever the reason for building a church within a Neolithic henge, the curious pairing has undoubtedly contributed to the survival of both, as an enduring symbol of the transition from pagan to Christian worship.
