Nave with N aisle, chancel, W tower with Hertfordshire spike. Construction is of flint and pebble with ashlar facings. The 12thc. S nave doorway, protected by a porch, has a figural tympanum. Access has not yet been possible, but Pevsner reports a Norman font.

In 1086 the largest landholder was the Abbot of Ely with a manor of 2 hides and 3½ virgates. In addtition, 2 knights held 1 hide and 22 acres of Count Alan, Pirot held 5 acres from Eudo fitzHubert, Hardwin de Scales held 1 virgate and 10 acres, Ralph held 3 virgates from Picot of Cambridge, and a priest held half a virgate from Countess Judith.

Browne's identification of the tympanum figures as episodes from the birth and death of St John the Baptist is worth summarising here. He read the scenes from R to L as follows:

1. The altar at which Zacharias burned incense (Luke 1, 9)

2. Zacharias standing before

3. the Angel

4. Herod's daughter dancing before

5. Herod

6. John the Baptist

7. the headsman's block

8. the severed head

9. figure carrying a charger

10. the head rising heavenwards.

In the absence of anything better, or indeed anything else at all, Browne's interpretation must be accepted.
