South Willingham is a village and civil parish in the East Lindsey district of Lincolnshire, England, and partly within the Lincolnshire Wolds Area of Outstanding Natural Beauty, . It is situated south of the A157 Lincoln to Louth road, west of Lincoln, where the central Lincolnshire Vale and the Lincolnshire Wolds meet. Its population was 160 at the 2011 census, down from a maximum of 341 in 1851. The village is mentioned in the Domesday Book but nearby long barrows and pottery finds provide evidence of settlement before this time. There are 7 listed buildings in the village, which include the Church and the two thatched cottages in the centre. The church clock still chimes on the hour. A tower windmill located at the edge of the parish was demolished in 1958. The village's two Methodist Chapels and school have now been converted to dwellings. South Willingham railway station, on the branch line from Bardney to Louth, closed in the 1950s, however a regular bus service currently calls at the village centre. Much of the village formed part of the Heneage Estate; Hainton Hall is a mile north of the village. At South Willingham is Belmont transmitting station, the second tallest structure in the UK. The geology under the village is unusually complex with four separate bedrocks located within the parish. Sand, gravel and clay have all be quarried in the parish; the clay pit supplied a brickworks in the Victorian era. History There are four bowl barrows at the east of the parish adjacent to the B1125 High Street; two within the parish boundary, and two just outside with one each in Gayton le Wold and Burgh on Bain (at ). The latter appears in Historic England's 2021 Heritage at Risk report. These Bronze Age burial mounds date from 2400 to 1500 BC. Aerial photographs and early OS Maps show evidence of further barrows, now destroyed, north-east from Inns Farm which is north-west from the village on Hainton Road close to the neighbouring parish of Hainton. A Royal Observer Corps nuclear monitoring post was installed in the bowl barrow on the High Street, close to the junction with the Donington Road in 1959. Officially known as the Burgh on Bain Post, it was used until 1991. In 1964 Beaker Pottery dating from about 1150-1400BC was found close to the sand pit at the end of Moors Lane. Willingham derives
