Timber features both inside and outside of St Mary's Church, Shenfield. The belfry - one of over one hundred in Essex - is white weather-boarded and probably fifteenth century in date. Inside, at the west end of the Nave, it stands on sturdy posts. The north aisle piers are not of stone or brick but of oak also. Other examples are at Theydon Garnon and Upshire, but Shenfield is probably the earliest example.
