Fillingham Grade II* listed Anglican church is dedicated to St Andrew.[1] Originally a building in Early English and Decorated style, it was largely rebuilt in 1777 with a new chancel and tower. It was further restored in 1866.[2] The earliest element is a c.1200 round-headed doorway in the west transept.[3] In the churchyard is a cross, 30 feet (9 m) high, dedicated to Major Thomas N. Dalton, killed in the Battle of Inkerman in 1854.[3]John Wycliffe was rector of the village from 1361 to 1368.[2]
There is evidence of a Roman camp in the village and Anglo Saxon pottery has also been found. Archaeological excavations have also found evidence of an Anglo Saxon cemetery which may have been associated with a second church in the village.[4]
