The church is situated within an oval churchyard in which a number of extremely old Yew trees can be found.

In the Middle Ages the church would have been a simple oblong, consisting of the nave and chancel, perhaps a tower.

Inside the church is a framed First World War Roll of Honour listing parish men who served, indicating those among them who died, how and when.

Nearby hang a picture and details of Selattyn's only Second World War loss, Robert Hanmer, killed returning from a bombing mission over Germany, with a display of his medals, pictures of the crash site and his grave.

There is a memorial from the Boer War, in the form of a brass plaque, to Trooper G. Evans (Imperial Yeomanry), who died of fever at Mafeking in 1900.

[4] Former rectors of the parish include Henry Sacheverell, who held the living from 1710 to 1713, despite having been suspended from preaching after being tried for politicised sermons he made in London.
