Just north of Holy Trinity parish churchyard is an Anglo-Saxonhlaew (barrow), about 59 feet (18 m) in diameter and 6 feet 7 inches (2 m) high.[4] It is a Scheduled Ancient Monument.[5] Worton has the remains of a medieval village cross. In the 20th century it was restored as the parish war memorial.[6]
Over Worton has had a parish church since at least the 13th century. The earliest known record of it is from 1254.[3] It had a Normanfont, which is now in St John's church, Hempton.[9] In the 1820s Over Worton's curate was the evangelical priest Walter Mayers, who in the 1800s had taught classics at Great Ealing School in what was then Middlesex. His pupils had included John Henry Newman, who then went up to Oxford University. In 1824 Newman was ordained as a Church of Englanddeacon at Christ Church Cathedral, Oxford. It was at Over Worton in 1824 that Newman preached his first sermon, and thereafter served on several occasions.[3] In the 1840s the curate was William Wilson, an evangelical whose family had owned the manor of Over Worton since 1799. In the 1840s Wilson had the medieval church demolished and the present Church of England parish church of the Holy Trinity built in its place.[3] It is a Gothic revival building, designed by the architect JM Derick and completed in 1844.[10] The north tower was added in 1849 and has two bells.[3] In the churchyard east of the chancel is a pair of stone medieval coffin lids[11] that may be a remnant from the previous church. Other remnants are a memorial tablet and effigy inside the present church. The tablet is in memory of the lawyer Edmund Meese, who died in 1617. The effigy is of a late 16th- or early 17th-century lawyer, and may also represent Edmund Meese.[3] Until 2015 Holy Trinity was part of a single benefice with St James' church, Nether Worton.[12] In March 2015 Nether Worton and Over Worton parishes became part of the Benefice of Westcote Barton with Steeple Barton, Duns Tew and Sandford St. Martin and Over with Nether Worton,[13] also called the Barton Benefice.[14]
