Church of St. Nicholas, Baydon

The church was built primarily of flint rubble and limestone. The nave and the two bays of the south arcade are clearly 12th century. The tower was largely rebuilt in the 15th century and the vestry was replaced in 1853 with further works to the church taking place later in the 19th century. The three bells of St. Nicholas's Church are recorded in The Church Bells of Wiltshire by H.B.Walters. He records the first as "a poor bell; the only example of John Stares' work in the county, though he was an Aldbourne founder".

The chaplain of Baydon was murdered in 1249, although little is known about the details of this.

On the census day in 1851, congregations of 40 and 50 respectively attended the morning and evening services.

The belfry clock is a memorial to the nine men from Baydon who died in the First World War. It was dedicated to them on 16 August 1919. The belfry is reached by a spiral staircase.

The church is now classified as a Grade 2* listed building.

The parish registers from 1673, other than those in current use, are held in the Wiltshire & Swindon Record Office at Chippenham
