Later in the century windows were added to the lowest stage of the tower and to the west end of the nave.

[2] The spirelet is twisted; this was caused when a flagpole was tied to it in 1897 to celebrate Queen Victoria's Diamond Jubilee, and it was damaged in a gale.

To the west of this is a timber-framed porch with a gable and plaster rendering including a small section of pargeting.

This leads to the Norman doorway, which is decorated with chevrons, and its tympanum contains a rare stepped cross.

[3][5] In the chancel is a long desk with copious graffiti, of particular note are two small coffins with skeletons visible inside.

The most recent item in the nave is a depiction of Christ drawn by a look-out soldier during World War II.

[5] In the churchyard are two tombs, one bearing dates in the 19th century, the other without an inscription, which are designated as Grade II listed buildings.

Many had fallen or were in danger of doing so, and the yard is now in the care of Duxford Parish Council who invariably found it easier to maintain.

There is a "no mow' policy in place for most of the year in certain parts of the churchyard excepting access up to and around the church.

Volunteers put on summer events at St John's including classical concerts, book launches, poetry readings and masterclasses.

Private tours are available on request, and the church has an annual visit by the village primary school, as well as the local scout group.

A series of four local films were made in Duxford in 2023, one of which was called "Thoughts and Prayers", now available on YouTube.
