Fillingham is a village and civil parish in the West Lindsey district of Lincolnshire, England. It is situated 9 mi north from the city and county town of Lincoln, and just over 1 mi west from the A15 road. Fillingham Grade II* listed Anglican church is dedicated to St Andrew. 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. The earliest element is a c.1200 round-headed doorway in the west transept. In the churchyard is a cross, 30 ft high, dedicated to Major Thomas N. Dalton, killed in the Battle of Inkerman in 1854. John Wycliffe was rector of the village from 1361 to 1368. 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. Fillingham Castle is a castellated mansion built in 1760 by Sir Cecil Wray. A nearby stone manor house was built about a century before. Fillingham Lake is one of the sources of the River Till, a small river whose lower reaches form the Fossdyke Navigation.
