File:Digby (Lincs), St Thomas' church (26347948112).jpg

The church is thought to date to the 11th century onwards. The south-east quoin of the nave demonstrates 11th century long-and-short work, while the south doorway is Norman. The long-and-short quoins may indicate that this was a church of some status by the early eleventh century, with potential minster status. The lower stages of the tower, the north and south aisles (both having three bays) and the chancel are of Early English date. The bell-openings in the tower, the windows of the north aisle and the east window of the south aisle are Decorated, while the clerestory and tower-top are Perpendicular. The church was restored by Charles Kirk in 1881, when the chancel was rebuilt.

The church is built in coursed limestone rubble and ashlar, with slate roofs. It has an unbuttressed three-stage tower, an octagonal stone spire with lucarnes, and gargoyles. The font is octagonal, of 15th century date. A piscina and sedilia can be found in the chancel, which has an encaustic tile floor.

Most fittings are 19th century except some 15th C. bench ends.
