Two ancient roads pass through the parish: the ancient Icknield Way at the foot of the Chiltern Hillsescarpment and The Ridgeway along the top. Both have been roads since at least the Iron Age.[2] Early in the 1970s archaeological investigations prior to building of the M40 motorway through the parish found traces of a Romano-British settlement near the village and a Romano-British cemetery near Icknield Way.[3]
Church Farm has a timber-framed barn that is mid- or late-14th-century. There have been suggestions that it is a former Medieval hall-house,[4] but they have been disputed.[5] It is a Grade I listed building.[6] Early in the 1970s archaeological investigations prior to building of the M40 motorway through the parish found traces of a large Medieval farmhouse high in the Chilterns in the east of the parish, on the alignment onto which the Christmas Common road was to be diverted.[3][7]
Parish church
Documentary and architectural evidence indicates the Church of England parish church was built some time after 1146 and before 1200. It was dedicated to Saint Mary but at some date was rededicated to Saint Margaret. It was originally a cruciform building with a chancel, nave, north and south chapels and a west tower.[8] The chancel arch, north chapel, two lancet windows in the nave, the font and some other features survive from this time.[2]
Early in the 14th century the building was enlarged in the Decorated Gothic style with a south aisle that absorbed the south chapel, and the chancel was enlarged and received new windows including the present east window.[2] In the chancel is a memorial effigy of a lady that also dates from the 14th century.[8]
In the 15th century a new Perpendicular Gothic west tower was built.[8] In 1553 the tower was recorded as having four bells and a Sanctus bell.[2] The four bells were replaced by a ring of five cast by Ellis I Knight of Reading, Berkshire[9] in 1636.[10] The Sanctus bell was replaced with a bell cast in 1744, possibly by Henry III Bagley[10] of Chacombe, Northamptonshire, who at the time had a foundry in Witney.[9] In 1950 the ring was increased to six with the addition of a new treble bell cast by Mears and Stainbank of the Whitechapel Bell Foundry.[10]
Lewknor was a strip parish that historically included three townships or divisions: Lewknor, Postcombe and Lewknor Uphill. Lewknor Uphill consisted of three detached parts in the Chiltern Hills: Ackhampstead, Cadmore End and Studdridge.[2] Ackhampstead was transferred to Buckinghamshire by the Counties (Detached Parts) Act 1844. Cadmore End became a separate parish in 1852 and Studdridge was transferred to Stokenchurch, but both places remained in Oxfordshire until they were transferred to Buckinghamshire in 1896.[12]
In 1836 All Souls College paid for a village school to be built next to the churchyard. This became a National School. In 1929 it was reorganised as a junior school, and senior pupils from the village were thereafter schooled at Chinnor. From 1859 the school was vested in the Vicar and churchwardens, and since 1950 it has been a voluntary controlled school.[2][13]
Transport
In 1869–72 the Watlington and Princes Risborough Railway was built through the parish. It ran right past the village but the nearest station it provided was 1 mile (1.6 km) away at Aston Rowant. The Great Western Railway took over the line in 1883 and built Lewknor Bridge Halt right next to the village in 1906.[14]British Railways withdrew passenger services and closed the halt in 1957.[15] Aston Rowant remained open for freight only until 1961, when British Railways withdrew this service and removed the track south of Chinnor cement works.
Early in the 1920s the Watlington — Chinnor road through the village was classified B4009. In 1974 the M40 motorway was built through the parish, passing just east of the village on an embankment. A bridge carries the embankment over the former railway trackbed, which has been reused to divert the B4009 to bypass the village. (This diversion also resulted in the staggered junction between the A40 and diverted B4009). M40 junction 6 between the motorway and the B road was formed here. South of the village the motorway climbs the Chiltern escarpment in a cutting up to 150 feet (46 m) deep[3] with steep chalk faces. The minor road linking Christmas Common with the A40 road near Stokenchurch was diverted slightly eastwards which is now carried across the cutting on a bridge formed of a single concrete arch 180 feet (55 m) wide.[3] Lewknor Turn on the M40 is a stop on the Oxford Tube coach service, which provides the village with frequent non-stop coach services to Oxford and London.
Air crash
On 31 March 1944 a Handley Page Halifax Mk III bomber aircraft, LW579 of No. 51 Squadron RAF, was returning from the Nuremberg Raid when it crashed in Cowleaze Wood, in the Chiltern Hills about 1+1⁄2 miles (2.4 km) southeast of Lewknor village, killing all seven of its crew.[16] LW579 was based at RAF Snaith in the East Riding of Yorkshire and seems to have been at least 120 miles (190 km) off course. It was a clear, moonlit night, and it is not clear why the Halifax lost height and crashed into the hill.[17] There is a monument in Cowleaze Wood to the crew of LW579.[18] In 2015 BBC Radio Oxford broadcast a documentary about the crash, the crew and some of their surviving relatives.[19]
Area of Outstanding Natural Beauty
In 1965 the Chilterns including the escarpment and hills in the parish were declared an Area of Outstanding Natural Beauty.[20] On the escarpment on either side of the motorway is Aston Rowant National Nature Reserve, which despite its name is partly in Lewknor parish. The reserve has beech woodlands, chalk grassland supporting diverse rare plants and butterflies, and is one of the best places in England to see red kites.[21]
