The oldest surviving parts of St. Micheal's church at Knill are the masonary in the chancel and nave walls and one window in the north wall which are Norman from the late 12th century. The font is also from this period. The tower was added in the 13th century and was probably used as a watch tower in addition to its religeous purpose. The south doorway also dates from this time.

The churchyard cross is 14th century, although it was restored along with much of the church by the Victorians. More recently the head cross was broken off and lost but a replica was made in 1976 from an old photograph. The churchyard is a very peaceful and quiet place and contains some spectacular trees.
