The remainder of the church externally dates from the restoration of 1889 by James Piers St Aubyn.

His Victorian Gothicisation of many churches and houses has been decried in terms ranging from vandalism to ruthless.

Little Horwood church was lucky, as the interior survived relatively unscathed, as did the early 16th-century wall paintings depicting the seven deadly sins, the Jacobean pulpit and the Decorated Gothic chancel arch.

The Tower has a ring of five bells, with a tenor of 9cwt 2qtrs 22lbs, tuned to the note of G. The manor of Little Horwood anciently belonged to the abbot and convent of St Albans, but was seized by the Crown with the Dissolution of the Monasteries in the mid-16th century.

The Grade II listed Little Horwood Manor is a comparatively modern house, designed by A. S. G. Butler in 1938 for the industrialist George Gee.
