All Saints has a three-bay aisled nave with a S transept, and a square chancel all in ashlar and roughly coursed stone rubble; and a brick W tower. The aisles, chancel and transept all belong to the mid to late 13thc., and the tower to c.1600, but the oldest parts of the magnificent chancel arch date from the 1120s, and the N priest's doorway and the two reset nave doorways date from c.1190. The round-headed aisle windows appear to date from c.1600 rather than 12thc., as does the porch protecting the N doorway. There is a 12thc. plain font, and a single chevron voussoir was discovered built into the W wall of the N nave aisle.

Morborne (5 hides) was held by the Abbot of Crowland in 1086. The church and a priest are noted.

Now benefice of Stilton (St Mary Magdalene) with Denton and Caldecote, and Folksworth with Morborne and Haddon.

The chancel arch cannot originally have been pointed, but the modification has been carefully done and very little disruption is visible. The reset voussoir is a mystery as it belongs stylistically with neither the chancel arch nor the doorways.
