Single nave with timber bell turret at W and wooden S porch on a stone base, lower square-ended chancel. There are opposing N and S doorways. The church appears to date from the early 13thc., but the chancel arch and font are described below

Beedon was held by the Abbey of Abingdon both before and after the Conquest. In 1066 it was assessed at 20 hides and Northmann held it from the abbot, and in 1086 it was assessed at 10 hides and Walter de la Riviere held it from the abbot. 1 hide of this land was held by Alwine in 1066 and Ansketil in 1086. The Domesday Survey records a church, a mill and 100 acres of meadow there too.

Walter de Riviere, or Rivers, and his descendants held the manor from the abbey until the 13thc, and in the early 14thc the Lord was named as Warine de Lisle, who forfeited his lands and his life for treason in 1322.

The church was a chapel of Chievely until the 16thc.

The chancel arch probably dates from c.1220, but is included on account of its waterleaf capitals. The font, being plain, is essentially undateable but may have come from an earlier church on the site.
