North Killingholme is a small village and civil parish in North Lincolnshire, England. Situated on the southern bank of the Humber Estuary north-west of Grimsby, Killingholme is divided into two administrative districts, to its south being the civil parish of South Killingholme. The harbour of North Killingholme Haven, and the Humber Sea Terminal (2000–) are in the northern part of the parish, on the banks of the Humber Estuary. The Lindsey Oil Refinery (1968–), and the Killingholme A and Killingholme B power stations (1990s–) are in the parish, north-east of the village. South Killingholme village is located south-west of the oil refinery – it is small in both area and population – the church of St Denys dates from the Middle Ages, and adjacent are the remains of two moated sites, formerly belonging to the Booth family who were lords of the manor and patrons of the living of Killingholme until Victorian times. The former RAF North Killingholme is in the southern part of the civil parish, built and used during the Second World War. Geography The parish of North Killingholme extends from the Humber Estuary foreshore roughly south-west through Lindsey Oil Refinery; the village of North Killingholme; and the former RAF North Killingholme to a boundary with the civil parish of Ulceby formed by the canalized water course, Skitter Beck. The parish is roughly long (north-west to south-east) and wide, widening to wide at the banks of the Humber. The drain outfall, harbour and port of North Killingholme Haven is in the northernmost corner of the parish on the Humber banks. To the south-east is the civil parish of South Killingholme; to the north-west is the civil parish of East Halton. North Killingholme is low-lying land, rising slowly from less than above sea level near the Humber to maxima of over to the south-western edges. A local peak of is found close to the church in the middle of the parish. Approximately 50% of the land area of the parish is in industrial or logistical use: land in industrial use includes the Humber Sea Terminal at North Killingholme Haven; the Lindsey Oil Refinery, and its two power stations adjacent north-west of the site (see Killingholme A and Killingholme B); as well as industrial estate development near the disused former RAF airfield. Much of the remainder of the parishes land is in agricultural use, with regular enclosed fields drained by
