The Grade I listed Anglican parish church in Navenby is dedicated to Saint Peter.
Despite parish registers existing from 1681, and Bishop's transcripts that go back to 1562, it is difficult to date the building as it has a mishmash of styles, although its origins are probably 13th century.

St Peter's is made up of three parts, including a mid-19th-century west tower, which replaced the original in 1859–60 after it fell down.
The perpendicular clerestory is decorated with shields in quatrefoils and is lit with closely set three-light windows.
The tall decorated chancel has very large windows.
The side windows have reticulated tracery.
The large east window was partly rebuilt in 1875–76, and is composed of six lights with two large mouchettes nodding to each other, as well as a very large reticulation unit.

The sedilia and piscina are thought to date back to William de Herleston, who was rector of St Peter's from 1325–29.
He was Edward I's chancellor and later became Canon of Llandaff.
A founder's tomb, which is in a slightly different style, is probably that of his successor, John de Fenton, who was rector until 1832.
The font is a lavish Victorian affair by Charles Kirk Junior, which was shown at the 1862 International Exhibition in London.
The Pulpit is Jacobean and the Rood screen by Temple Moore dates from 1910.
The Royal Arms are signed "Thomas Hunton of Lincoln.
Painter 1710."
There is a late 13th-century grave slab, with an inscription in Norman script which says "Pray for Richard de Lue" (Louth).

The church also contains an Easter Sepulchre.
The carving is recognised as one of the finest in Lincolnshire, if not in the country, and receives a mention in virtually every book written on churches and their architecture.
The churchyard is managed as a nature reserve.

In 1982, church officials threatened to close St Peter's Church after being refused permission to sell silverware to pay for urgent repairs.
The Archdeacon, Michael Adie, ruled that such sales were against church policy and that funds must be raised locally.
