The name Swillington is first attested in the Domesday Survey in the forms "Suillictun", "Suilligtune" and "Suillintun". Its etymology is uncertain, but probably derives from Old Englishswīn "pig" + either lēah "open ground" or hyll "hill" + ing, a suffix which in this case marks the word as a place-name + tūn "estate, farm". The Dictionary of British Place Names gives a derivation from "farmstead near the pig hill." The name was recorded as "Svilentone" in 1147. Historically Swillington's full title was Swillington-in-Elmet, which refers to the association of the village with the early medieval polity of Elmet. However, as with many other places the "-in-Elmet" has been lost in modern times with only a few exceptions such as Barwick-in-Elmet and Sherburn-in-Elmet surviving. Nowadays Elmet only exists as a political constituency.
Economy
Swillington sits at the centre of an agricultural community, and includes Leventhorpe Vineyard and an organic farm. Leventhorpe Vineyard, established in 1986, is near the village, and has been recommended by Rick Stein. It was until recently the most northerly commercial vineyard in Britain—there is now one further north, near Malton. The Soil Association-certified organic farm on the former Lowther estate has been frequented by celebrity chefs, and has produce voted the 'Best Meat In Yorkshire' in 2007.
Landmarks
Swillington sits on the banks of the River Aire, and is adjacent to the RSPB St Aidan's Nature Reserve. The parish church of St Mary is a Grade II* listed building of 14th- or 15th-century origin, with Victorian additions. Leventhorpe Hall, within the parish and to the west of the village, is a Grade II* listed house built in 1774.
Transport
Swillington does not have a railway station, unlike the nearby town of Garforth, but is served by bus operators. The major roads through the village are Wakefield Road, Swillington Lane and Astley Lane. Under proposals released on 28 January 2013, Phase 2 of the High Speed 2rail link would be built close to the western side of the village, running adjacent to the M1 motorway. The HS2 track would cross the existing railway line close to Thorpe Park to the north of the village and also cross Selby road via embankment and bridge. Further south a viaduct would be placed across Wakefield Road. This line would carry the spur away from Leeds, towards the East Coast Main Line at Church Fenton.
The village has four local football teams, a bowls team, snooker teams and a rugby league team. They use recreational grounds surviving from the mining days. There is also a shooting and country sports supply business in town, and a number of horse riding stables. Swillington Church also host many groups, including a keen bell ringing team. Being on the Leeds Country Way, the area surrounding Swillington, including the River Aire, the Aire and Calder Navigation and the woods of Temple Newsam house are used for cycling.
